Porous silicon (PS) has been synthesized by anodic etching in HF and ethanol electrolyte. The in situ current-voltage characteristic clearly identify the pore formation, transition and electropolishing regimes. The experimentally observed impedance and phase as a function of frequency (Bode plots) reasonably agree with theoretically simulated Bode plots drawn by considering the equivalent circuit for PS/electrolyte.
