21. A method of making a substantially flexible porous semiconductor material comprising:
-
introducing a semiconductor substrate into an electrochemical etching bath;
applying a current density for a sufficient duration to achieve a porous region of the semiconductor substrate; and
second applying a sufficiently high current density to cause electropolishing of an interface between the porous region and a remainder of the semiconductor substrate, wherein said second applying releases the porous region from the remainder of the semiconductor substrate. - View Dependent Claims (22, 23, 24, 25)
