Abstract: 

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 were examined.

Keywords: 
Porous GaAs, AFM, impedance spectroscopy, Nyquist plots.
