Dielectric response of metallic crystal made up of highly polarisable molecules: the semi-classical approach
AbstractThe dielectric response is considered within models of a one-band metal, a two-band insulator and a two-band metal using the semi-classical approximation. Corresponding dielectric functions are found. The dielectric function of two-band metal is found to be the interpolation between the Sellmeyer and Lorenz-Lorentz expressions, respectively. The frequencies of the collective modes are identified as the zeroes of the dielectric functions. The correspondence between the semi-classicaldoi:10.2478/s11534-008-0160-8 fatcat:cfagnmzopbcuxmqnnigw3ywh4m
