Abstract
A normal-incident SiGe/Si multiple quantum wells photodetector was reported. The structure and fabrication process of the photodetector were introduced. The photocurrent spectra measurement showed that the response spectra was expanded to 1.3 micrometers wavelength. The quantum efficiency of the photodetector was 0.1 percent at 1.3 micrometers and 20 percent at 0.95 micrometers .
