Abstract
A solid-state semiconductor photonic device is prepared by a photoelectrochemical deposition method. The device contains a highly conductive coating material including one or more metals and/or semiconductors on a substrate containing a semiconductor material. The device is utilized in photodetectors, including radiometric detection cells, in conversions of electrical energy to optical radiation, such as light-emitting-diodes and diodes lasers, and in photovoltaic cells, including Schottky-barrier cells.
