A SiGe/Si Heterojunction Phototransistor for High Sensitivity Light Detection

Silicon-based heterojunction phototransistors (HPTs) with their advantages of high internal gain, high responsivity, and compatibility with CMOS processes have attracted much attention in high-sensitivity light detection. In this article, the SiGe/Si HPT with an illuminated area of 50\times 50~\mu...
