Graphite/n-CdTe Schottky-type heterojunctions were prepared by means of a very simple and low-cost method: the drawing of graphite films on the rough surface of mechanically polished n-CdTe single crystal substrates. The unoptimized heterojunctions showed promising, rectifying, and photoelectrical parameters. The obtained results represent a good starting point for the further development of the simple and low-cost heterojunction photodiodes and gas sensors.
