Abstract
Bevels through Si/SiGe structures were prepared by chemical etching. The surface of the bevels was smooth and bevel angles were in the range 10-4 rad. From the Raman spectra along the bevels the thickness and composition of SiGe alloys were determined and compared with photocurrent response spectrum of the structures.
