Abstract

A Chemical Etching Solution for the Determination of the Crystallographic Orientation of GaSb by Optical Reflectograms.-Etching of GaSb surfaces with a solution of 1.0 N CuCl in conc. HCl produces sharp figures on the low index planes, (111), (110), and (100) , which allow the optical orientation with an accuracy comparable with that obtained by using X-rays. In particular, the reflectograms obtained from the (111)A and (111)B surfaces are clearly different and allow their easy identification. -(GODINES, J.
