The invention relates to a process and apparatus for formation and deposition of thin films on a substrate, in a vacuum, by evaporation of the elements to form a Zn /SUB x/ Cd/sub 1//sub -/ /SUB x/ S compound having a preselected fixed ratio of cadmium to zinc, characterized by the evaporation of cadmium and zinc at a rate the ratio of which is proportional to the stoichiometric ratio of those elements in the intended compound and evaporation of sulfur at a rate of at least twice the combined rates of cadmium and zinc, and at least twice that required by the stoichiometry of the intended compound.
