ABSTRACT
Examines the photoabsorption spectra of silicon-silicon germanide (Si-SiGe) quantum-well (QW) infrared photodetectors. Observation of lower dark current in Si-SiGe QW detectors; Superiority of Si-SiGe over GaAs-AlGaAs QW detectors; Comparison of absorption peak shift induced by electron-electron interactions and depolarization effect.
