High‐Detectivity GeSn Mid‐Infrared Photodetectors for Sensitive Infrared Spectroscopy

High‐Detectivity GeSn Mid‐Infrared Photodetectors for Sensitive Infrared Spectroscopy

Infrared (IR) spectroscopy is a powerful, nondestructive analytical technique that requires cost‐effective and highly sensitive IR photodetectors (PDs). Herein, complementary metal‐oxide‐semiconductor (CMOS)‐compatible GeSn p–i–n PDs with record‐high detectivity (D*) are presented, offering a broad...
