摘要：
We report on optical spectroscopies performed on porous SiC obtained by electrochemical etching of 6H-SiC wafers. Strong modification of Raman and Infrared spectra are ascribable to surface states peculiar of the porous structure. The emission properties of the etched specimens are analyzed by stationary Photoluminescence spectra and show marked differences with respect to the bulk non-porous samples.
