Abstract
An infrared photodiode structure is provided. The infrared photodiode structure includes a doped semiconductor layer having ions of certain conductivity. An active photodetecting region is positioned on the doped semiconductor layer for detecting an infrared light signal. The active photodetecting region includes one or more amorphous semiconductor materials so as to allow for high signal-to-noise ratio being achieved by invoking carrier hopping and band conduction, under dark and illuminated conditions.
