Abstract

The anodically etched porous silicon carbide (PSiC) was analyzed for blueshifted emission. Peak cathodoluminescence (CL) emission wavelengths in the ultraviolet were produced in the PSiC due to high etching current densities. Different emissive states were accessed in CL and photoluminescence (PL), as PL was also blueshifted but not to the extent of CL. The formation of new surface which harbored surface states responsible for the distinctive properties observed was also elaborated.
