The temperature dependence of the Raman spectra of silicon nanocrystals (nc-Si) in a SiOx matrix has been studied. The temperature evolution of the phonon spectra is considered as a result of the combined influence of the phonon-confinement effect, anharmonic phonon coupling, thermal expansion, and...
