Porous GaAs was formed electrochemically on n-type GaAs in a HF:C₂H₅OH (1:3) electrolyte. The surface morphology of porous GaAs has been studied using atomic force microscopy (AFM). The hodographs of the total impedance and the adsorption influence of ethanol and acetone vapor on the charge transfer...
