Abstract :
Current transport model and current gain degradation mechanisms of a silicon heterojunction bipolar transistor with amorphous SiC emitter are discussed by observing various characteristics of amorphous SiC films as the emitter material. Under such study current gain is remarkably enhanced by using low resistance micro-crystalline Si, and current gain as high as 480 has been obtained.
