You can use the diamond paste to roughen the surface.  This is commercially
available.  RIE etching  is OK.  Good luck!  Ram

Subject: [mems-talk] How to make texturing surface for ZnSe

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.
