10GHz Surface Acoustic Wave Filter Fabrication by UV Nano-Imprint

Chen H.J.H., Chen N.H., Chen H.J.H., Chen N.H., Lin C.H., Huang F.S., National Tsing Hua University, TW

Surface acoustic wave (SAW) devices have been widely implemented for wireless communications. Recently, SAW devices continue the upward trend in frequency for higher functionality. Nanoimpirnt can adequately offer mass production technique on interdigital transducer (IDT) [...]

A simple route to synthesize impurity-free high-oriented SiOx nanowires

Chiu S.C., Li Y.Y., National Chung Cheng University, TW

Impurity-free silicon oxide nanowires were synthesized on a 3 cm x 3 cm alumina plate uniformly by thermal evaporation of a mixture of powder of graphite powders and Si-SiOx particles under argon atmosphere with a [...]

Growth _–Fe2O3 nanowires with different crystal direction of iron film

Hsu L.C., Li Y.Y., National Chung Cheng University, TW

–Fe2O3 nanowires (NWs) were synthesis from different crystal direction of iron film by thermal oxidation in oven. The crystal direction of iron film was successfully control by sputtering 50 nm iron on different direction of [...]

Morphological, Crystalline and Photo-luminescent Property of Zinc Oxide Nanorod Array Controlled by Zinc Oxide Sol-gel Thin Film

Huang J-S, Lin C-F., National Taiwan University, TW

Our work provides a systematic study of controllable morphology, crystallinity and photoluminescence (PL) of ZnO nanorod array. Our investigation demonstrates that the pre-treatment conditions of the ZnO sol-gel thin-film have strong influences on the morphology, [...]

Low Turn-On Voltage and High Focus Capability Nanogaps for Field Emission Displays

Kuo Y-T, Lo H-Y, Li Y., National Chiao Tung University, TW

Nanometer scale gaps (nanogaps) has been wildly used as electrode in molecular electronics [1,2], biosensor [3], and vacuum microelectronics [4]. However, the difficult from the fabrication limits the development of such technique until the surface [...]

Experiments and Simulations of Infrared Transmission by Transverse Magnetic Mode through Au Gratings on Silicon with Various Air-slot Widths over the Period

Chen Y-R, Kuan C.H., National Taiwan University, TW

Au gratings with various air-slot widths were fabricated experimentally by electron beam lithography system (e-beam) and their infrared (2.5~25 m) transmission of the transverse magnetic mode (TM mode) were investigated by the Fourier Transform Infrared [...]

The anti-ultraviolet nano-fibers formed during electrospinning

Lin Y-N., Hsu R-Q., Chang K-M, National Chiao Tung University, TW

In this study, electrospinning is a straightforward method to produce anti-ultraviolet polymer fibers. The new types of anti-ultraviolet nano-fibers were produced by polylactic acid (PLA) and benzophenone. We also used different anti-ultraviolet nano particles (TiO2, [...]

The First-aid strip of copolymer, produced by electrospinning

Lin Y-N., Hsu R-Q., Chang K-M, National Chiao Tung University, TW

In the study of biomimetic material design, mimicking nanostructured thin film components can take the place of the extracellular matrix. The new types of thin film were fabricated by polylactic acid (PLA) and hyaluronic acid [...]
