查询词典 emitter

Current peaks for different spins in the Ⅰ-Ⅴ curve split. The confined"light"hole energy levels of the QW turn out to be an effective tunnelling channel for both"heavy"and"light" holes. Although considerable tunnelling current originate from the"heavy"hole state in the emitter region, the current in the collector is mainly carried by the"light"hole state.

无论对重空穴还是轻空穴来说，量子阱中轻空穴的束缚能级都是有效的隧穿通道，虽然隧穿电流有相当大比例由发射极重空穴态提供，但在集电极端大部分电流又由轻空穴态传导。

In this study, AlGaN/GaN hetero-junction photo-transistors in detecting ultraviolet spectra have been fabricated and characterized. One of the HPTs features as low-temperature grown GaN insertion layer between based and emitter layers to reduce dark current. The internal gain and response time are also studied for the HPTs with and without the LT-GaN layer.
