Abstract

Selective Wet-Etching of Amorphous/Crystallized Sb-Se Thin Films The paper is focused on the development of an in situ real-time method for studying the process of wet chemical etching of thin films. The results of studies demonstrate the adequate etching selectivity for all thin film SbxSe100-x (x = 0, 20, 40, 50, 100) compositions under consideration. Different etching rates for the as-deposited and laser exposed areas were found to depend on the sample composition. The highest achieved etching rate was 1.8 nm/s for Sb40Se60 samples.
