Electric field distribution and field emission current over the surface of point (sphere-on-cone) and wedge-shaped defects on a plane substrate are studied. It is found emission current due to wedge-shaped defects is more sensitive to emitter-anode distance than in case of point conical defects. This property is consequence of greater emission area of wedge-shaped defects and has important prac...

Although Li-ion battery is one of the most widely used energy storage devices, there have been extensive efforts to push its limit meet ever increasing demands increase density for applications such as electric vehicles, portable electronics, and grid storages. Here, lithium metal anode plays a key role in next generation ultimately enabling anode-free configuration. However, are major challeng...

This paper presents a magnetically sensitive transistor using a nc-Si:H/c-Si heterojunction as an emitter junction. By adopting micro electro-mechanical systems (MEMS) technology and chemical vapor deposition (CVD) method, the nc-Si:H/c-Si heterojunction silicon magnetically sensitive transistor (HSMST) chips were designed and fabricated on a p-type <100> orientation double-side polished silico...

Transistors are three-terminal devices that use a small voltage (or current) applied to one contact to modulate (i.e. control) a large voltage (or current) between the other two contacts. An analogy is the vacuum tube from the 1900s. A small voltage applied to the 'grid' modulates a large current between the anode and cathode. The bipolar junction transistor The BJT (1947) is a minority carrier...

Type II InP/GaAsSb transistors have attracted much interest in high speed microelectronics. However, Kirk-effectinduced current blocking was observed, limiting the highest achievable current density and hence the speed. In this work, we present an explanation as to the cause of current blocking in InP/GaAsSb DHBTs. The effects of collector thickness are investigated and methods to achieve highe...

objectives: the purpose of this study was to evaluate whether intra-canal application of controlled direct electric current (dec) could accelerate the amount of orthodontic tooth movement (otm) in young adult mixed breed dogs. methods: fourth premolars of both jaws of five young adult mixed breed dogs were divided into two groups of control and experimental groups. orthodontic force was applied...

The thermal power industry is the largest coal consumer, and contribution of its air pollutants to PM2.5 has become a hot topic public concern, which worthy in-depth study. There are total 32 generation enterprises in Jilin Province, 19 coal-fired enterprises, accounting for 59.37%. Based on investigation analysis basic situation five typical have been identified as research objects. In general...
