Abstract

Planer type Schottky-type diodes were prepared using CuAlS2 single crystal with evaporated metal contacts of Al and Au. Prior to evaporation the crystals were mirror-polished and etched in HF for 30s. Optical absorption spectra were changed by application of the electrical field to the Al-CuAlS2-Au diode.

Key words:

CuAlS2, Schottky diode, electrically induced change of absorption
