An improved functional ZnSe1-xTex:H film having a high doping efficiency and with no substantial change in the characteristics upon light irradiation. Said film is characterized in that the Se/Te quantitative ratio is in the range from 3:7 to 1:9 by the atom number ratio hydrogen, atoms are contained in an amount of 1 to 4 atomic % and the ratio of the crystal grain domains per unit volume is in the range from 65 to 85% by volume. There are also provided improved p-type and n-type ZnSe1-xTex:H:M films (M stands for a dopant) of high electroconductivity characterized in the foregoing way. These deposited films may be efficiently deposited even on a non-single crystal substrate made of metal …
