InN dielectric function from the midinfrared to the visible range
L. A. Falkovsky
The dispersion of the dielectric function for wurtzite InN is analytically evaluated in the region near the fundamental energy gap. The real part of the dielectric function has a l…
Infrared absorption and Raman scattering on coupled plasmon--phonon modes in superlattices
L. A. Falkovsky, E. G. Mishchenko
We consider theoretically a superlattice formed by thin conducting layers separated spatially between insulating layers. The dispersion of two coupled phonon-plasmon modes of the s…
Effects of disorder on the Raman line-shape in ZrO_2
L. A. Falkovsky
Experimental data obtained by Lughi and Clarke [J. Am. Ceram. Soc., 88, 2552 (2005)] are compared to the theory describing disorder effects on optical phonons. Sharpening and vanis…
Raman scattering on phonon-plasmon coupled modes in magnetic fields
L. A. Falkovsky
Raman scattering on phonon--plasmon coupled modes in high magnetic fields is considered theoretically. The calculations of the dielectric function were performed in the long-wave a…
Electron-phonon interaction and coupled phonon--plasmon modes
L. Falkovsky
The theory of Raman scattering by the electron--phonon coupled system in metals and heavily doped semiconductors is developed taking into account the Coulomb screening and the elec…
Damping of coupled phonon--plasmon modes
L. A. Falkovsky
The effect of free carriers on dispersion and damping of coupled phonon-plasmon modes is considered in the long-wave approximation. The electron and phonon scattering rate as well…
