Planer type Schottky-type metal-semiconductor diodes were prepared using CuAlS2 single crystal with evaporated metal contacts of Al and Au. It is found that optical absorption spectra can be changed by application of the electrical field to the Al-CuAlS2-Au diode. This change in the absorption is attributed to the change in the valence of the transition atom impurities due to the movement of Fermi level caused by electric field.
