Abstract

A novel solution growth methodology for fabrication of amorphous, red selenium thin films and their conversion to the hexagonal, gray modification is presented. The method is based on deposition process from aqueous solution of selenosulfate by citric or ascorbic acid as oxidizing agents. The X-ray diffraction method is used for identification of the deposited materials. Ultra-thin films of both amorphous and hexagonal selenium are highly transparent in the Vis–NIR spectral region.
