aThe current in a reverse-biased diode is small (typically 10-8 A for silicon) and approximately independent of voltage until the breakdown region at high reverse voltages is reached. 潮流在一个reverse-biased二极管是小 (典型10-8 A为电压的) 硅和近似地独立,直到击穿范围在高反向电压被到达。 [...

One embodiment of the invention provides a semiconductor diode device including a first conductivity type region, a second conductivity type region, where the second conductivity type is different from the first conductivity type, an intrinsic region located between the first conductivity type region and...
diode is intended in particular to a generatrix of the alternating current. < / p & gt; & lt; p & gt; it comprises an insulating element in the form of a disk - interposed between a tail, and a body. It is intended to be mounted on a rotating element, parallel to the axis of ...
We studied the transverse structure of electron current in resonant tunneling diodes (RTDs). The coherent transport of electrons, which is described by Tsu-Esaki formula, induces zone-center current flow of electrons in RTDs. By comparison, the coherent transport of holes has off-zone-center curre...
Using specially prepared structures, we have observed emission from a layer of direct-gap "monitor" material placed between thep-contact layer andp-cladding layer of a conventional 670 nm GaInP laser diode at room temperature. This observation provides direct evidence for electron leakage through thep...
P Kumar,A Jain,M Shukla,S Chand 摘要: The space charge limited current (SCLC) in a Schottky diode with a finite injection barrier at the injecting contact and single level traps in the energy space has been investigated by mathematical modelling. Solution of coupled Poisson's and continuity ...
Theoretical and experimental study of the frequency characteristic of rectified current in a rectifier circuit employing a semiconductor diode with an active load at large signal level. Within the framework of diffusion theory and without accounting for the pn junction capacitance, the rectified current ...
An analytical theory is given for the space-charge-limited (SCL) current of an electron diode in the presence of collisions. It extends the improved SCL current formula, which already takes into account the effect of nonzero electron injection velocitiesv0,by treating collisions within a simple ...
