晶体管和各种整流器件都是利用了半导体的P-n结或金属-半导体接触的本质的特性而制成的器件,与此相对应,利用半导体体内所发生的物理现象制成的器件一般叫作体效应器件。其典型是只在均匀半导体晶体的两端加欧姆性电极的器件、耿效应器件(有时它也与体效应器件等同——狭意的体效应器件)、超声波放大器件、等离子体器件等是体效应器件的代表例子。 Transistors and various rectifying devices are devices that make use of the intrinsic characteristics of semiconductor Pn junctions or metal-semiconductor contacts. Correspondingly, devices made from physical phenomena occurring in semiconductors are generally referred to as bodies Effect device. It is typically a device that only adds Ohmic electrodes on both ends of a uniform semiconductor crystal. Ginger effect devices (sometimes it is also equivalent to body effect devices - narrow body effect devices), ultrasonic amplification devices, plasma devices, A representative example of an effect device.
