摘要
回顾了异质结光晶体管(HPT)在近年来的重要进展,综合分析了HPT的工作原理以及影响其性能的主要参数。综述了不同材料制作的HPT的研究现状,得出了目前限制HPT发展的主要因素及当前应重点解决由于基区表面复合等效应导致的增益下降和由于结电容的充放电限制的响应带宽等问题的结论。
The main progress of heterojunction phototransistors (HPT) are reviewed. And the principle, key parameters are presented. Based on the present researches of HPT applied for optical receiver with different materials, it reveals that some problems should be solved such as the decline of the gain resulted from the base surface recombination and the response bandwidth limited by the charge and discharge of junction capacitance.
