This SPIE paper by Hall and Handel investigates 1/f noise in the dark current of GaN Quantum Well Infrared Photodetectors (QWIPs). The research analyzes low-frequency fluctuations in the leakage current of gallium nitride based infrared detectors, which limits detection sensitivity particularly at low frequencies relevant to imaging and tracking applications, showing how quantum 1/f noise contributions in the dark current establish fundamental noise floors for GaN QWIP focal plane arrays in thermal imaging and night vision systems.
