munication systems because of their high probability of intercept, and their simultaneous processing of multiple signals in real-timely. They also have many merits such as simple structure, light weight and low cost. Recently, to realize optical transmission system with lager capacity and high-speed, an optical module with high performance, low cost and small size is strongly required. In this ...

In order to evidently improve the working performance of piezotronic devices, non-uniform piezoelectric semiconductor fibers with contoured profiles are designed. However, apart from finite element method, it's hard achieve analytical descriptions electromechanical fields in these because governing equations variable coefficients. For solving this bottleneck and exploring improved new phenomena...

Diluted ferromagnetic III-V semiconductors typically show a high degree of compensation. Compensation is connected to the presence of comparable densities of charged defects of either sign. This naturally leads to the development of strong correlations between defect positions during growth and annealing. We show that these correlations are required to understand the experimentally observed tra...

Piezoelectric thin films are of current interest in science and industry for highly integrated nano-electro-mechanical-systems sensor devices. In this study, the dependence piezoelectric properties on doping concentration Si:HfO2 their crystallographic origin investigated. The with a thickness 20 nm various Si concentrations range 2.7–5.6 cat.% were examined. relationship between displacement r...

The hybridization of semiconductor optoelectronic devices and nanomechanical resonators provides a new class of optomechanical systems in which mechanical motion can be coupled to light without any optical cavities. Such cavity-less optomechanical systems interconnect photons, phonons and electrons (holes) in a highly integrable platform, opening up the development of functional integrated nano...

An electric field built inside a crystal was proposed to enhance photoinduced carrier separation for improving photocatalytic property of semiconductor photocatalysts. However, a static built-in electric field can easily be saturated by the free carriers due to electrostatic screening, and the enhancement of photocatalysis, thus, is halted. To overcome this problem, here, we propose sonophotoca...
