Hi --

Does anyone happen to have John Choi's procedure for mixing HBr etchant 
for anisotropic etching of InP or GaAs?  As I recall, it was very 
detailed and he had worked with a chemist to ensure that no Br2 would be 
generated...  (Angie Lin from the Harris lab wants to do this -- her 
protocol is very vague -- she plans to do this in the Harris lab, not SNF.)
