Transferring porous layer from InP wafer based on the disturbance

Abstract

We present a new method to transfer the three dimensional (3D) porous layer from InP wafer based on the disturbance, during electrochemical etching of n-InP (100) with chronopotentiometry with current ramp in 3 mol-L−1 NaCl solution. The potential bursting phenomenon was observed due to the disturbing instantaneously. In addition, the correlation between the amplitude of the potential and the porous layers separated from the InP wafer was discussed.
