I synthesized 6H-SiC (bulk) pellet and took temperature dependent Raman measurement of that. Now I want to take temperature dependent Raman measurement of pellet of nanocomposite of Epitaxial Graphene-6H SiC pellet. What kind of Raman spectrum change I can expect in pellet of nanocomposite of Epitaxial Graphene-6H SiC pellet with respect to 6H-SiC pellet? All relevant answers and suggestions are appreciated!
Hi Arpan, I don't know if this will help, but the only Raman spectroscopy reference I have on SiC and graphene is from L. Malard et al.Article Raman Spectroscopy in Graphene
There are some interesting discussions on the topic and I believe it will be an initial reference for you.
Good look on your research!
Dear Arpan Ghosh ,
A change in temperature, for any kind of study, implies a change in the phonon modes. In Raman spectroscopy, an increase of the temperature always induces a shift of the Raman bands to lower frequencies (see DOI: 10.1038/srep32236). This affact is attributed to thermal expansion and anharmonic effects of phonon processes
