Hello, everyone As we know, we can make texturing structure (pyramids) on Si by simple wet etching. Is there anyone knowing that how to make the texturing surface for ZnSe? Or some other ways to roughen the surface of ZnSe? The purpose is to scatter the light and increase the light absorption.What I am thinking about is using RIE etching or mechanical roughen. I don't know whether is possible or not. Regards Weiquan Yang Arizona State University
