High-detectivity and low-cost short-wave infrared photodetectors with complementary metal−oxide−semiconductor (CMOS) compatibility are attractive for various applications such as next-generation optical communication, LiDAR, and molecular sensing. Here, GeSn/Ge multiple-quantum-well (MQW) photo-dete...
