Abstract
Abstract There is provided a functional ZnSe:H deposited film composed of zinc atoms, selenium atoms, and at least hydrogen atoms, with the content of hydrogen atoms being 1 to 4 atomic % and the ratio of crystal grains per unit volume being 65 to 85 vol %. It is capable of efficient doping and is stable to irradiation. It can be made into a high conductivity p-type of n-type ZnSe:H:M film by doping. It can be efficiently deposited on a non-single crystal substrate such as metal, glass, and synthetic resin which was incapable of efficient depositing. Thus the invention makes it possible to form a high-functional device such as a photovoltaic element of ZnSe film on a non-single crystal substrate.
