Transmission characteristics of metallic ultrathin film for optical color filter


We analyzed transmission characteristics of two-dimensional periodic corrugated silver thin film by calculating the transmission spectra and the intensity distribution. It is aimed for the development of optical filter having wavelength selectivity and high transmission efficiency by surface plasmon resonance. The geometrical parameters defining structure were optimized by calculations using finite-difference-time-domain (FDTD) algorithm. The silver plasmonic filter, which consisted of corrugation period of 400 nm and film thickness of 130 nm, exhibited 25.9 % transmittance at the wavelength of 544 nm.

Chang Sih-Wei Award Candidate Using Metal-less Structure to Enhance the Raman Singals of Graphene by 100-fold while Maintaining the Band-to-Band Ratio and Peak Positions Precisely


We developed a method to analyze the interference-enhanced Raman scattering (IERS) effect on graphene by controlling surface electric field. Through optimizing the one-dimensional photonic crystals (1D-PhCs), the Raman signals of single layer graphene can be enhanced up to 150 times without the distortion of both band-to-band ratio and peak position.

Chung-Hua Yu Award Candidate Transparent, Broadband, Flexible, and Bifacial-Operable Photodetectors Containing a Large-Area Graphene-Gold Oxide Heterojunction


In this study, we combine graphene with gold oxide (AuOx), a transparent and high-work-function electrode material, to achieve a high-efficient, low-bias, large-area, flexible, transparent, broadband, and bifacial-operable photodetector.

Ya-Chen Chang Award Candidate Increasing the Transmittance of Superhydrophilic Thin Film with Favorable Abrasion Resistance


Transparent superhydrophilic thin film was prepared by a two-layer structure (TiO2+SiO2/SiO2). In particular, when a SiO2 layer was inserted between TiO2+SiO2 and the substrate, the average transmittance in the 400-700 nm wavelength was increased. This experimental consequence is compared with the results of a simulation.

Ting-Yang Chen Award Candidate Thin Film Transistor-Based Biosensors Combined with Microfluidic Channels for Detecting Protein-Ligand Interactions


We demonstrate a thin film transistor-based biosensor combined with microfluidic channel for detecting protein-ligand interaction between MDH and NADH. Due to concentration gradient in the solution, the bio-molecules diffuse to the sensing pad through a microfluidic channel. The diffusion and electrical signals of MDH and NADH are measured respectively. Then the protein-ligand interaction is detected by our TFT biosensor.
