Abstract: A method of forming an oxide-based nano-structured material by growing a nano-structured material using a nano-nucleus having the same composition as the desired oxide-based nano-structured material. A solution is coated on a substrate by dipping, spin or spray coating. The solution includes an organic precursor containing a transition metal or a semi metal and an organic solvent in which the organic precursor is dissolved. A metal oxide nano-nucleus is then formed on the substrate by annealing the substrate. A metal oxide nano-structured material is formed by growing the nano-nucleus while supplying a reaction precursor containing the same metal as the formed oxide into the nano-nucleus. Methods used for this step include PVD, CVD and sol gel processes. The nano-structured material is finally annealed. The structure can be used in an electronic device such as a diode, a display, FET, SET or a battery.

Abstract: Provided is a microelectromechanical system (MEMS) actuator in which a cantilever piezoelectric actuator and a comb actuator are combined to perform dual shaft drive. The MEMS includes: a stationary comb (10) fixed on a substrate; a movable comb (11) disposed separately from the substrate; and a spring (12) connected to the movable comb and the substrate to resiliently support the movable comb, wherein the movable comb includes a piezoelectric material layer (111d) in a laminated manner to be perpendicularly moved by a piezoelectric phenomenon and laterally moved by an electrostatic force to the stationary comb, whereby the MEMS actuator can be used in a driving apparatus of an ultra-slim optical disk drive since the movable comb is made of a piezoelectric material to simultaneously perform focusing actuation to a Z-axis as well as planar actuation.

Abstract: Provided are a structure for an optical device and method of fabricating the same. The structure includes: a light scattering layer producing nanoparticles due to externally provided thermal energy; a protective layer protecting the light scattering layer; and a capping layer disposed between the light scattering layer and the protective layer. As the light scattering layer is formed of nitride-oxide, an energy gap is increased to make the structure suitable for a high-speed electronic circuit, and a desired stoichiometric ratio can be easily obtained. Also, the capping layer prevents crystalline mismatch, thus the non-uniformity of elements is inhibited to maintain a stoichiometric state. As a result, a high-integrated high-speed electronic circuit, which is excellent in uniformity and reproducibility, can be easily embodied.
