Photoluminescence and Raman spectroscopy in porous SiC

This paper presents results of porous SiC characterization using photoluminescence, Raman scattering and Atomic Force Microscopy. A comparative optical spectroscopy study on bulk SiC and porous SiC layers has shown a number of new features specific to nano-crystallite materials. The role of these effects on optical spectroscopy data in porous SiC accessed by photoluminescence and Raman scattering is discussed.
