Optical properties of graphene
- L. Falkovsky
- Physics
- 23 June 2008
Reflectance and transmittance of graphene in the optical region are analyzed as a function of frequency, temperature, and carrier density. We show that the optical graphene properties are determined… Expand
Space-time dispersion of graphene conductivity
- L. Falkovsky, A. Varlamov
- Materials Science, Physics
- 30 June 2006
Abstract.We present an analytic calculation of the conductivity of pure graphene as a
function of frequency ω, wave-vector k, and temperature for the
range where the energies related to all these… Expand
Optical far-infrared properties of a graphene monolayer and multilayer
- L. Falkovsky
- Materials Science, Physics
- 10 July 2007
We analyze the features of the graphene mono- and multilayer reflectance in the far-infrared region as a function of frequency, temperature, and carrier density taking the intraband conductance and… Expand
Electron-lattice kinetics of metals heated by ultrashort laser pulses
- L. Falkovsky, E. Mishchenko
- Physics
- 1 February 1999
We propose a kinetic model of transient nonequilibrium phenomena in metals exposed to ultrashort laser pulses when heated electrons affect the lattice through direct electron-phonon interaction. This… Expand
Symmetry constraints on phonon dispersion in graphene
- L. Falkovsky
- Physics
- 7 February 2008
Abstract We calculate the phonon dispersion for graphene with interactions between the first, second, and third nearest neighbors in the framework of the Born–von Karman model taking into account the… Expand
PHYSICS OF OUR DAYS: Optical properties of graphene and IV-VI semiconductors
- L. Falkovsky
- Physics
- 1 September 2008
The frequency dispersion of the dynamic conductivity of graphene, of a multilayer graphene, and of IV–VI semiconductors is considered as a function of the temperature and carrier density in the range… Expand
Optical properties of doped graphene layers
- L. Falkovsky
- Materials Science
- 4 May 2008
The reflectance of a graphene monolayer, as well as of a system of monolayers, is calculated in the infrared range. A quantum expression for the conductivity in the collisionless regime that depends… Expand
Phonon dispersion in graphene
- L. Falkovsky
- Materials Science, Physics
- 17 February 2007
Taking into account the constraints imposed by the lattice symmetry, we calculate the phonon dispersion for graphene with interactions between the first and second nearest neighbors. We show that… Expand
Magneto-optics of monolayer and bilayer graphene
- L. Falkovsky
- Materials Science, Physics
- 21 March 2013
The optical conductivity of graphene and bilayer graphene in quantizing magnetic fields is studied. Both dynamical conductivities, longitudinal and Hall’s, are analytically evaluated. The… Expand
Strain effect in silicon-on-insulator materials: Investigation with optical phonons
- J. Camassel, L. Falkovsky, N. Planes
- Physics
- 29 September 2000
We report a detailed experimental and theoretical investigation of the effect of residual strain, and strain relaxation, which manifests itself at the Si/SiO2 interfaces in commercial… Expand
