Abstract
A photodetector useful at long wavelengths where silicon normally is transparent. It includes a photodiode stage which comprises a silicide layer forming a Schottky-barrier junction with a silicon substrate and which is integrated with an amplification stage which uses a silicon transistor adapted to amplify the photovoltaic voltage derived by the photodiode stage. In the preferred embodiment, the silicide layer forms the grid of a permeable base transistor.
