Formation of porous layers on n-GaSb by electrochemical etching

The effect of electrochemical etching of n-type GaSb in aqueous solutions of HCl and HF has been analysed. By anodization in HCl, two different morphologies of porous layers were observed depending on the current density. At low current density (0.5 mA cm_(-2)) a macroporous layer is formed with the...
