N型和P型半导体的取名

当加电压时,N型半导体表现出来是由带负电的电子导电的,P型则表现出来由带正点的空穴导电。。。可以直接理解为一个是负电荷导电,一个是正电荷导电,所以一个是Negative一个是Positive

electron 带负电negative,n-type (nnnnn negative);hole为正电荷 positive,p-type (pppp positive)。

"Extrinsic semiconductors with a larger electron concentration than hole concentration are known as n-type semiconductors. The phrase \u0026#39;n-type\u0026#39; comes from the negative charge of the electron. "…"As opposed to n-type semiconductors, p-type semiconductors have a larger hole concentration than electron concentration. The phrase \u0026#39;p-type\u0026#39; refers to the positive charge of the hole. "http://en.m.wikipedia.org/wiki/Extrinsic_semiconductor
