Popis: | The theory of multiple quantum well n-type Si-SiGe IR detectors is presented. The coefficient of photoabsorption, quantum efficiency and responsivity of Si-SiGe quantum well detector are calculated taking in consideration the effects of depolarization and electron-electron exchange interaction. We show that the Si-SiGe quantum well detectors possess lower dark current and better performance characteristics compared to GaAs-AlGaAs photodetectors. |
