pn结(p-njunction)
在一块n型(或p型)半导体单晶上,用适当的工艺方法(如合金法、扩散法和离子注入法等)把p型(或n型)杂质掺入其中,使这块单晶的不同区域分别具有p型和n型的导电类型,在二者的交界面处就形成了pn结。pn结刚形成时,p区的多数载流子空穴向n区扩散,在n区边界附近与电子复合。p区失去空穴,在其边界附近就剩下带负电的受主离子;同理,n区电子也向p区扩散,在其边界附近剩下带正电的施主离子。结果在p区和n区交界面的两侧形成带正、负电荷的区域,称为空间电荷区,也叫耗尽区(多数载流子缺乏)。空间电荷区内正、负离子电荷总量相等,其中形成的电场方向由n区指向p区,它就是pn结的自建电场。在平衡时,自建电场的大小正好能阻止空穴和电子进一步扩散,使空间电荷区宽度保持一定。当结上加正向电压时(即p区接电源正极,n区接负极),自建电场削弱,使多数载流子(p区的空穴,n区的电子)容易通过pn结,因而电流较大,这时pn结叫做正偏结,电流称为正向电流;当结上加反向电压时,内建电场增加,只有少数载流子(p区的电子,n区的空穴)易通过pn结,因而电流很小,这时pn结叫做反偏结,电流叫做反向电流。pn结具有单向导电性,这是pn结最基本的性质之一。pn结这种整流特性是很多半导体器件和电路的核心。整流器及许多其他类型的二极管都是只含1个pn结的器件;一般结型晶体管是2个pn结构成的器件;晶体闸流管是含有3个或4个pn结的器件。
