Nonlinear Raman-Nath diffraction(NRND)is a unique diffraction pattern formed when a high-intensity laser interacts with a nonlinear microstructure bulky medium relying only on the transverse phase matching condition.H...
We present an approach of GaAs MESFET incorporating the gate engineering effect to improve immunity against the short channel effects in order to enhance the scaling capability and the device performance for microwave...

Modulation caused by surface/subsurface contaminants is one of the important factors for laser-induced damage of fused silica. In this work, a three-dimensional finite-difference time-domain (3D-FDTD) method is empl...
The effects of the physical damages induced by heavy ion irradiation on the performance of partiallydepleted SOI devices are experimentally investigated. After heavy ion exposure, different degradation phenomena are o...
Submicron stripe-shaped InGaN light-emitting diode (LED) arrays with individually addressable capabilities are demonstrated. The critical submicron- stripe metallic electrodes, which define the emission pattern, are...

Direct laser writing technique has become a well-established, multi-functional and flexible method for fabricating high quality diffractive optical elements. We propose and build a maskless direct laser writing system...
Tunneling is studied in two main single-photon avalanche diode (SPAD) topologies, which are r^-tub guard ring (NTGR) and p-tub guard ring (PTGR). Device sinmlation, I - V measurements, and dark count calculation...
We report the direct synthesis of ZnC0204 and ZnO/ZnC0204 submicron rod arrays grown on Ni foil current collectors via an ammonia-evaporation-induced method by controlling the ratio of Zn to Co. These three-dimension...
A bimodal effect of transconductance was observed in narrow channel PDSOI sub-micron H-gate PMOSFETs,which was accompanied with the degeneration of device performance.This paper presents a study of the transconductanc...
ZnO nanoparticles were first encapsulated in submicron PS hollow microspheres through two-step swelling process of core-shell structured PMMA/PS (PMMA: polymethyl methao- rylate) microspheres in acid-alkali solutio...
