一、本征晶体管场效应晶体管不同于典型的(两个结:PNP 或 NPN)晶体管,在第一种近似的情况中,它们的工作原理与晶体中的少数载流子无关;根据这个理由叫做单极晶体管。(在具有两个结的晶体管结构中,少数载流子至少与多数载流子有同样重要的作用,则这些晶体管就称之为双极型的)。实际上,存在着两种不同类型的单极晶体管:结型和绝缘栅型。现在的倾向是:把结型的称之为场效应晶体管,把绝缘栅型的称之为 MOS 晶体管(金属-氧化物-半导体,构成栅 1. Intrinsic Transistor Field-effect transistors differ from the typical (two-junction: PNP or NPN) transistors. In the first approximation, they work on a minority carrier in the crystal; for this reason they are called Unipolar transistor. (In the transistor structure with two junctions, the minority carriers are at least as important as the majority carriers, then these transistors are called bipolar). In fact, there are two different types of unipolar transistors: junction and insulated gate type. The current tendencies are: the junction is called a field-effect transistor, the insulated gate type is called MOS transistor (metal-oxide-semiconductor, constituting the gate
