Abstract

Metal-modified amorphous arsenic selenide films were prepared by spinning a solution containing an amine salt, thioacetamide and chlorides of the impurifying metals Zn, In, Sb, Co and V on thoroughly cleaned flat glass substrates. X-ray analyses show excess total metal components for the V- and Co-modified films whilst the In-, Zn- and Sb-doped films are selenium-rich. The electrical conductivity and optical absorption measurements reveal that only the transition metals V and Co have significant effects on the transport. A narrowing of the optical band gap as well as the conductivity activation energy is observed as the impurity concentration is increased
