查询词典 diode

When the diode is forward biased, electrons are able to recombine with holes and energy is released in the form of light. This effect is called electroluminescence and the color of the light is determined by the energy gap of the semiconductor.

随着成长，他也会拥有一个可以盛放自己秘密和隐私的地方，也许是抽屉（但在当今社会更可能是电脑）或许还是房间……但抽屉的概念依然存在；广义的讲，每个人都可以比作是一个"抽屉"。

When the diode is forward biased, it begins to conduct with only a small forward voltage across it, which is on the order of one volt.
