Ga2O3/Ag/Ga2O3-laminated films with high electrical conductivity and ultraviolet (UV) transparency were achieved by radio frequency magnetron sputtering at room temperature (RT) on quartz glass. The influence of annealing ambient the structural, optical properties investigated in detail. As increases, bandgap Ga2O3-laminated widens. exhibited good photoelectric performance a figure-of-merit (FO...

This paper presents a comprehensive comparison of three state-of-the-art heterojunction bipolar transistors (HBTs); the AlGaAs/GaAs HBT, the Si/SiGe HBT and the InGaAs/InP HBT. Our aim in this paper is to find the potentials and limitations of these devices and analyze them under common Figure of Merit (FOM) definitions as well as to make a meaningful comparison which is necessary for a technol...

A D-shaped photonic crystal fiber (PCF) temperature sensor based on surface plasmon resonance (SPR) with high sensitivity and figure of merit is presented in this paper. To enhance resonance, the gold film deposited polished flat fiber. Ethanol chloroform are employed as temperature-sensitive materials, which placed outside to detect changes. When phase-matching condition met, core mode couples...

Herein, two simple configurations of Fano resonance-based plasmonic sensors are proposed for temperature and biosensing applications. The device optimization sensing performance numerically investigated via two-dimensional finite element method (2D-FEM). former configuration is quite based on the side-coupled circular cavity (SCCC), whereas in latter, encapsulated ring separated by a small gap ...

Vibration energy harvesters (VEHs) allow the extraction of ambient mechanical energy. The proposed analysis focuses on bistable with Duffing nonlinearity. Bistable exhibit larger frequency bandwidth than linear monostable harvesters, but they complex behaviors (i.e., multiple periodic orbits and chaos), making their evaluation challenging. To assess quality a VEH, it is necessary to evaluate it...

This paper proposes a mem-computing model of memristive network-based genetic algorithm (MNGA) by building up the relationship between network (MN) and (GA), new edge detection where image pixels are defined as individuals population. First, computing MNGA is designed to perform mem-computing, which brings possibility hardware implementation GA. Secondly, MNGA-based integrating filter GA operat...
