Polycrystalline-Si/GaAs interfaces have been prepared by depositing hydrogenated amorphous Si (a-Si:H) onto GaAs in a silane plasma at 450 °C and annealing temperatures between 600 1020 °C. Rutherford backscattering, secondary ion mass spectroscopy, transmission electron microscopy show that the resulting polycrystalline-Si/GaAs interface is metallurgically stable when undoped while significant interdiffusion occurs 12 at. % As added to Si. The data are consistent with Greiner/Gibbons theory...
In previous reports of the literature, ZnO nanoparticles were unexceptionally used as electron transportation material in highly efficient CdSe-based quantum dot light-emitting diodes (QD-LEDs). However, an amphoteric oxide, are chemically unstable air. Here, we utilize quantum-sized SnO2 layer (ETL) QD-LEDs. Decreasing size will upshift conduction band from -4.50 to -3.84 eV based on effect, which is beneficial facilitate injection into QD emitting layer. Our investigations show that...

Flexible tactile sensors have promising applications at the field of intelligent robotics. However, manufacturing flexible with excellent stability and high sensitivity remain a great challenge. In present work, polyvinylidene fluoride (PVDF)-based nanofibers are prepared by electrospinning loaded Fe3O4 nanoparticles (NPs). X-ray diffraction (XRD) attenuated total reflection Fourier transform infrared spectroscope (ATR-FTIR) results indicate that addition NPs promotes generation...
The low pressure chemical vapor deposition of in situ phosphorus‐doped polysilicon films from and was investigated a production‐type hot wall horizontal tube reactor as function mole ratio temperature. With increasing partial pressure, reduction growth rate is observed because the dissociative chemisorption inhibited. reaction proceeds via homogeneous gas phase reactions which explains that, our case where we operate at relatively high about 1 torr, limited to factor 2 (87–45 Å/min). By...

This paper tackles the problem of noise suppression during vital sign signal monitoring. Physiological monitoring is a significant and promising medical method, wearable devices based on piezoelectric polymer sensors are trending way for their advantages being flexible in shape, portable to use, comfortable wear. However, this raises question that measured contains much more components. To avoid following shortcoming low ratio (SNR), method improved wavelet threshold empirical mode...
interfaces have been prepared by depositing hydrogenated amorphous Si (a‐Si:H) onto in a silane plasma at 450°C and annealing temperatures between 600° 1050°C. Rutherford backscattering, secondary ion mass spectroscopy, transmission electron microscopy analyses show that the resulting interface is metallurgically stable when undoped, while significant interdiffusion occurs P or As are added to Si. The diffusion into rapid ( 1000°C) depends on concentration increases with increasing content...
Accurate measurement of rock electrical properties plays a crucial role in resource exploration and geological exploration. But there are kinds problems with traditional measuring electrodes including high contact resistance, electrode polarization, low stability so on. To solve these problems, we designed fabricated an all solid-state polarizability stability. The consists silver (Ag) chloride (AgCl). reduce the resistance between rocks, was by powder sintering repressing, scanning electron...
A new type of Ag/AgCl electrode as a marine electric field sensor is prepared using electrospray. The surface the porous, and particle size AgCl small uniform with an average 1.43 µm, which accelerated speed oxidation–reduction reactions. Therefore, large specific area has high stability low noise. impedance, sensitivity, self-noise, are measured to study electrochemical performance electrode. impedance 7.9 Ω, shows resistance characteristics, meaning that can well receive weak ocean signals...

A physical model of velocity-overshoot hot-carriers based on the balanced equation energy is developed and implemented in MOSFET models. Derived from Boltzmann equation, a simple analytic simulation can be put into BSIM3 model. There are better identical verifications among velocity overshoot, standard (not including effects overshoot) real device data.
