Novel approach to Raman spectra of nanoparticles
S. V. Koniakhin, O. I. Utesov, I. N. Terterov +3
In crystalline nanoparticles the Raman peak is downshifted with respect to the bulk material and has asymmetric broadening. These effects are straightly related to the finite size…

Substrate-induced reduction of graphene thermal conductivity
Sergei Koniakhin, Oleg Utesov, Ivan Terterov +1
We develop the theory of heat conductivity in supported graphene, accounting for coherent phonon scattering on disorder induced by an amorphous substrate. We derive spectra for in-…
