Zhen-Hong Yang Award Candidate Hybridization Models of Gold Nanoantennas Arrays in Evanescent Waves
Zhen-Hong Yang,Yu-Lun Kuo,Che-Yuan Chang,Yi-Hsun Chen,Kuo-Ping Chen,

Antibonding-plasmonic-dipolar modes of gold nanoantennas (NAs) are excited by evanescent waves. Comparing the resonance wavelengths of NAs by changing the length in transverse direction, blue shifting in resonance wavelengths is observed when the angle of incidence is larger than critical angle. Near-field distribution shows the transverse mode of NAs with TM polarization will always be bright modes in evanescent waves

Yi-De Chan Award Candidate Effects of silica nanoparticles Si-based photodiodes with Au-Ag surface plasmon resonance
Yi-De Chan,Jun-dar Hwung,

Effects of silica nanoparticles (NPs) on improving photo-response of Si-based photodiodes (PDs) with surface plasmon resonance (SPR) of Au-Ag NPs have been investigated. The silica NPs can enhance the photo-response by a magnitude of about 1.9 for the wavelength shorter than 650 nm. However the value is reduced to 1.75 for the wavelength longer than 650 nm. In contrast, the reduced photo-response is not found in the 400 oC annealed PDs due to rougher surface.

All the device preformance had been significant improved due to the plasmonic effects.

Chih-Chiang Yang,Yan-Kuin Su,

Pure ZnO and Ag–ZnO core–shell nanorods (NRs) were successfully synthesized via a low-temperature hydrothermal method, and as-prepared samples were characterized through low-magnification bright-field TEM image and selected-area electron diffractometry. The enhanced field-emission behavior of Ag–ZnO core–shell NRs along the [0002] crystal c-axis direction and their single-crystalline hexagonal structures were also characterized using surface-protruding Ag nanoparticles. Field-emission results exhibited a low turn-on electric field of 3.93 V/μm and field enhancement factor β of 1593.

Yi-De Chan Surface plasmon resonance of Au-Ag nanoparticles on the silicon-based p-n junction photodiode
Yi-De Chan,Jun-dar Hwung,

Surface plasmon resonances of Au-Ag nanoparticles (NPs) annealed at various temperatures (100~400 °C) was used to enhance the short wavelength response of silicon-based p-n junction photodiodes (PDs). With increasing annealed temperature of Au-Ag NPs, the short wavelength responsivity increases; however the higher annealed temperature (400 °C) results in a formation of Au-silicide, thus suppressing the responsivity. As compared to the PDs without Au-Ag NPs, the responsivity for the PDs with Au-Ag-NPs annealed at 300 °C is increased by a magnitude of 5.9 at 400 nm wavelength.

Wen-Hui Xu,Kai-Xiang Zhan,

Recently, graphene oxide(GO) has attracted considerable interest. Because it has some unique physical and biomedical characteristics, such as hydrophilic, biocompatibility and structural stability, it affords GO a distinct potential in biomedicine. Hence we combine GO with Cholesteric liquid crystal (CLC) to make vapor sensors for improving the sensitivity and response time of sensors.
