Prof. Teruo Ono(Institute for Chemical Research, Kyoto University), "Spin Dynamics in Inhomogeneously Magnetized Systems"
  Worldwide efforts are underway to create revolutionary and energy‐efficient data storage technology such as magnetoresistive random access memory (MRAM). An understanding of spin dynamics in inhomogeneously magnetized systems is indispensable for further development of nanoscale magnetic memories. This lecture provides a transparent picture of inhomogeneously magnetized systems, such as magnetic nanowires with domain walls and disks with magnetic vortices, and presents not only technological developments and key achievements but also the unsolved puzzles and challenges that stimulate researchers in the field.
  Firstly, the basic concept of an inhomogeneously magnetized system is described by introducing a magnetic vortex structure in a magnetic disk. A magnetic domain wall in a magnetic nanowire is also provided as a typical example. The magnetic field‐driven dynamics of these inhomogeneously magnetized systems are described to illustrate the uniqueness of this system. Secondly, the electric‐current‐induced dynamics of magnetic vortices and domain walls are described. One can flip the core magnetization in a magnetic vortex using electrical current excitation, and move a domain wall by current injection into a wire. The next part focuses on the applications of the current‐induced‐magnetization dynamics in devices. The basic operations of two kinds of magnetic memories—magnetic vortex core memory and magnetic domain wall memory—are demonstrated.
  The lecture describes not only the current understanding about inhomogeneously magnetized systems, but also the unexpected features that have emerged. It concludes with prospects on future developments, in which more surprises will certainly be found.

Yung-Chun Lee (Cheng Kung Univ.), "Roller-Based Nanoimprinting and Contact Printing Lithography for Fabricating Micro/Nano-Structures"
 Nanoimprinting technology was first developed in 1995 and is now recognized as one of the most promising approaches for large-area and low-cost fabrication of nanostructures. In this presentation, three types of roller-based nanoimprinting and contact-printing methods developed in NCKU in recent years will be addressed. First of all, a Laser-Assisted Roller Imprinting (LARI) method which can directly transfer the pattern from a quartz mold to a silicon substrate is introduced. The advantage of LARI is that the pattern transformation is direct, fast, and without any chemical etching processes. Secondly, a Light-Assisted Metal Film Patterning (LAMP) method which transfers a patterned metal film directly from a silicon mold to a substrate is discussed. The pattern transformation relies on both mechanical contact pressure and optical heating at the interface. Metal patterns with 100 nm feature size can be easily transferred in laboratory using simple equipments and setups. Finally, a Contact-Transfer and Mask-Embedded Lithography (CMEL) is proposed which cleverly arranges pure mechanical forces and surface energy difference to achieve the patterning of nano-structures on various kinds of substrates. Applications of these developed methods are also demonstrated on the fabrication of high-frequency surface acoustic wave (SAW) filters and resonators. Future developments and potential applications of these roller-based nanoimprinting and nano-patterning methods will be addressed.

Alexander Grishin (Department of Condensed Matter Physics Royal Institute of Technology, Sweden), "New Magneto-Optical Garnets, Frontiers in Oxide Photonics and Electronics"
1. New Magneto-Optical Garnets I present our results on processing and characterization of epitaxial magneto-optical (MO) garnet films and heteroepitaxial all-garnet MO photonic crystals. We work with completely substituted bismuth iron garnet Bi3Fe5O12 (BIG) which shows the record value of Faraday rotation (FR) as high as θF = -8.4 deg/μm @633nm and a peak value of -28 deg/μm @537nm. However, big lattice mismatch and different thermal expansion coefficients of BIG and commercially available substrates create insurmountable obstacles to achieve crack free 45° Faraday rotators. MO photonic crystals, first time fabricated by M. Inoue with co-workers, promise to further increase FR due to multiple light reflections in non-reciprocal MO-cavity. We use pulsed laser deposition and rf-magnetron sputtering techniques to grow heteroepitaxial 1D photonic crystals which compose of λ/4 garnet layers alternating highly gyrotropic BIG and MO-passive highly transparent rare earth gallium garnets: Gd3Ga5O12, Sm3Ga5O12, and novel La3Ga5O12. At the resonance wavelengths 750 (980) nm, [Bi3Fe5O12/Sm3Ga5O12]m photonic crystals demonstrate specific FR θF = ? 20.5 (? 7.3) deg/μm and MO-quality factor Q = 2│θF│/absorption = 66 (43.6) deg that are the highest MO-photonic crystal performance achieved so far. Respectively, this is 470 (810) % and 31 (190) % enhancement compared to a single layer BIG. Using atomic layer deposition we fabricate Bi3Fe5O12/Gd3Ga5O12 superlattices with a strong perpendicular magnetic anisotropy. They enable latching type (non-volatile) MO-switching. 2.5 μm thick Bi3Fe5O12/Gd3Ga5O12(3:2) film at 678 nm shows FR = ± 1.4 deg, transmittance 82%, 92% squareness of magnetization loop, saturation and coercive fields as low as 56 and 25 Oe, respectively. Nanostructured garnets were used to build MO-visualizer, current driven MO-display and have been integrated with glass substrates. 2. Frontiers in Oxide Photonics and Electronics I survey our research on ferroelectric and ferromagnetic films processing, properties, and device fabrication:novel lead-free biocompatible (Na,K)NbO3 ferroelectric films were demonstrated to be feasible for piezo-, microwave and electro-optic applications; low loss and uniquely low dispersive Ag(Ta,Nb)O3 films used for microwave varactors show superior properties compared to (Ba,Sr)TiO3 considered as a premier for microwave applications; the first PZT-based ferroelectric field effect transistor (FeFET) has been fabricated on SiC. Non-volatile operation has been demonstrated at elevated temperatures up to 300 °C; all-perovskite heteroepitaxial film structures combine different types of ordering: ferromagnetism, ferroelectricity, and high-temperature superconductivity. Magnetosensitive non-volatile (La,Ca)MnO3/Pb(Zr,Ti)O3 memory was demonstrated; thin (La,Ca,Pb)MnO3 film colossal magnetoresistors (CMR) were used to fabricate uncooled IR-bolometers with unique noise equivalent temperature difference NETD = 120 nK/√Hz. CMR films have been integrated with Si and GaAs. First time array of micromachined free standing CMR membranes for IR-bolometers was fabricated; nanocrystalline Er2O3 films exhibited strong broad C-band photoluminescence at room temperature.

 As the revolutionary development of the mechanical/electrical technology of 1980’s contributes highly to the advancement of industrial structure, the prediction, which the biotechnology would lead the advancement of 21st century industrial structure, has became the reality. The biotechnology is beyond the just technology in laboratory. It opens up the huge new markets. A front runner to open up the bio-market is the combined technology of bio and nano, which are the hot topic among the scientist worldwide. Scale down effect is the physical characteristics while miniaturizing and enables the breakthrough of bio research at the Micro-Nano level; biosensor using nanowire and carbon nanotube, real-time monitoring using quantum dot, and monitoring and controlling of a chemical reaction using SPM. A new scientific area, which requires deep scientific thinking and observation, would bring up new competitive scientists who will be the competitive power of the nation and lead to the future. In this seminar, I will explain the current trend of the nano-bio technology and show you few exemplary researches.

Stuart (Shizhuo) Yin(Associate Professor of Electrical Engineering The Pennsylvania State University), "Innovative fiber grating devices and their applications to reconfigurable communications and harsh environment sensing"
  In this talk, I will briefly present our recent work on fiber grating devices and their applications to reconfigurable communications and harsh environment sensing. Two types of novel fiber grating devices, including all-fiber ultra fast tuning speed tunable wavelength filter and fiber gratings in single crystal sapphire fibers, were recently developed in the Electro-Optics Lab at The Pennsylvania State University. The all-fiber ultra fast tuning speed tunable wavelength filter is composed of a unique single resonant band long period grating and second electro-optic cladding layer. The refractive index of second electro-optic cladding layer is tuned by the external electric field, which in turn results in a shift the spectral response of long period grating. The major advantages of this tunable filter are: (1) high tuning speed ~ ns range, (2) low insertion loss (all-fiber device), and (3) small footprint and cost effect. The harsh environment fiber optic sensor, in particular, the high temperature sensor (e.g., > 1500 oC), is based on the fiber gratings fabricated in single crystal sapphire fibers, which has the merits of high melting temperature (> 2000 oC) and chemical resistance. Thus, it is perfectly suitable for harsh environment sensing.

 Among several important issues in the realization of high density magnetic random access memory (MRAM), a wide window for bit-writing is of prime concern. In order to tackle this problem, a new method was recently proposed. Two essential ingredients of the new method are the use of the spin-flop phenomenon and a timed pulse sequence in the word and bit lines. There are two different modes of writing: the toggle and the direct write mode. Indeed, a very large switching window was claimed to be realized in the new method. However, the main drawback of the new method is a large switching field being up to several hundred Oe. Actually, this problem can be expected from a large threshold field for spin-flop. In this talk, some current issues of bit-writing for high density MRAM are discussed. A particular emphasis is given to the reduction of the switching field of the new method.

X. S. Zhao(Nat’l Univ. Singapore, Dept. of Chemical & Biomolecular Eng.), "Fabrication of 3D photonic crystals with self-assembled colloidal crystal as the template"
 Just as research in semiconductors led to a revolution in the electronic industry that we have witnessed over the later half of the 20th century, new materials known as three-dimensional (3D) photonic crystals (also known as photonic bandgap materials) promise a similar revolution in photonics - where photons of light rather than electrons are the fundamental carriers and processors for information.  Fabrication of 3D photonic crystals remains a great challenge. Conventional lithography techniques have trouble in making complex structures. On contrast, self assembly approach, which describes a spontaneous process by which colloidal spheres self organize into ordered arrays, offers many advantages over lithography methods. This talk discusses how the self assembly method works. In addition, a flow-controlled vertical deposition (FCVD) method for self assembly of colloidal crystals will be described. Fabrication of line defects embedded in a photonic crystal will also be presented. Furthermore, nanosphere lithography for surface patterning and preparation of nanostructures will be briefly discussed.

 Very small laser beams having a size 10 times smaller than the wavelength of light open up new opportunities for ultra-high density data storage and manipulation of molecules and atoms. Conventional laser beams with such small apertures have very low power output. Recently we have developed a new aperture shape that provides 1000 times more light throughput for the same spot size as a conventional round or square aperture. In this talk we will describe fundamental reasons why these apertures are so efficient, and we will illustrate applications in ultra dense optical data storage and in molecular chemistry and biology. For example, a pair of small beams can be used as optical tweezers to move or tag large polymer molecules. The tiny beams also provide extremely precise probes for tagging fluorescent molecules to sort fluids and polymers. Recent theoretical and experimental results in our laboratory will be presented. In the second part of the lecture, we will discuss technology transfer from Stanford University to industry via technology licensing and start-up companies. We will describe University policy, and give two examples of companies in which the lecturer ash been involved. The talk will emphasize the start-up process, the infrastructure required and the steps that go into forming a successful new venture. Potential conflict of interest issues, and ways to manage them, are addressed for faculty members and events that participate in the technology transfer process. Finally we describe how Stanford University has achieved a leadership position in Silicon Valley and around the world dealing with transfer of University developed technology to industry.

 We investigated Bragg diffraction patterns from high-quality synthetic opals with lattice spacing comparable to the wavelength of visible light. Diffraction patterns consisting of one, or two, or four spots as well as their transformation were observed on a screen by varying the crystal orientation and illumination wavelength. These spots resulted from the Bragg reflection of the monochromatic incident beam on the {111} ? type layers of the twinned face centered cubic structure of opals. It was demonstrated that diffraction experiments could provide a visual mapping of the photonic band structure.

Alfred Ludwig and Eckhard Quandt(Center of Advanced European Studies and Research), "Magnetostrictive multilayers for actuator and sensor applications"
 Fabrication, characterisation methods and applications of rare earth transition metal films with giant magnetostrictive and soft magnetic properties, will be presented. Optimised materials could be the base for various microactuators such as microfluidic devices, micromotors, micromirrors or -sensors e.g. for detecting mechanical stresses or magnetic fields. One of the key advantages of magnetostrictive microactuators is seen in the possibility of a remote operation. Examples of possible materials are amorphous Tb40Fe60 and Sm40Fe60 films and (Tb40Fe60 / Co50Fe50) multilayer films, having amorphous TbFe layers and crystalline FeCo layers. The most common deposition method is magnetron sputtering, the influences of the deposition parameters on the film quality will be addressed. Special post deposition treatments like magnetic field annealing are discussed with respect to an achievement of a well defined magnetic anisotropy. The magnetostrictive characterisation of the films is performed using an optical beam deflection method. This method derives the magnetoelastic coupling coefficient which is independent of the Young´s modulus of the film. The dependencies of the magnetic and magnetostrictive properties on the multilayer compositions will be explained as well as the temperature dependencies of the magnetostriction of these materials. Optimised (7 nm Tb40Fe60 / 9 nm Co50Fe50) multilayer films show a magnetoelastic coupling coefficient of 27 MPa at an external magnetic field of 20 mT and a coercive field of about 2 mT. Further effects like magnetoresistance and the DE-effect are investigated and the correlation to the magnetostrictive effect are presented.  High-frequency magnetic thin films with cut-off frequencies well above 2 GHz and good magnetoelastic properties are key materials for the development of new magnetic devices such as remote-interrogated magnetoelastic sensors or micro-inductors. In order to achieve high cut-off frequencies the films must have high magnetization, high anisotropy field, moderate permeability and resistivity. Therefore, multilayered thin films consisting of the transition metal alloy Fe50Co50 and the amorphous soft magnetic alloy Co80B20 have been developed which show cut-off frequencies higher than 2 GHz combined with good magnetoelastic properties. The results of the materials development are discussed in view of possible applications which are mainly in the area of microelectromechanical systems (MEMS).
