Surface modification of SB-SE thin films by laser irradiation and etching

Abstract

The surfaces of 20-80 and 40-60 thin films were modified by exposure to laser light. To study the topology of these surfaces the scanning force microscopy was used. As a result, the surface of as-deposited/amorphous 100-x films appear to be flat, while the treated films exhibit three types of surface structure on the sub-micrometer scale. Changes in the surface characteristics as well as potential applications of selective etching of Sb-Se thin films are discussed.
