MicroCrystal Silicon and Germanium Single Photon Avalanche Detectors Whilst CMOS single photon avalanche detectors (SPADs) are commercially available, the quantum efficiency is limited by the indirect bandgap and the thickness of the absorption region. At near infrared wavelengths where automotive rangefinding and LIDAR can most easily operate through fog and rain, expensive InGaAs technology limits […]
