宽带隙材料作发射区的异质结光晶体管（HPT）的研究

Study of the Heterogeneous Phototransistor(HPT) with a Wide-gap Emitter

本文在研究一种特珠结构的光晶体管──异质结光晶体管（ＨＰＴ）的工作原理基础上，分析用宽带隙材料作发射区，可减少注入损耗，提高增益的特性。

On the basis of the study of HPT working principle,the characteristic of reducing injecting loss and increasing the gain is analysed.
