Abstract
A new MSM photodetector, including a photoabsorbing layer of ternary or quaternary III-V compound semiconductor material, is disclosed. This new photodetector is significant because it exhibits a relatively small dark current and a correspondingly large signal-to-noise ratio. Moreover, the photodetector is readily integrable with electronic integrated circuits and is relatively easy to fabricate.
