Abstract

Optical properties of vanadium films have been investigated. Based on the measurements of reflection coefficient in 0.2 - 50 micrometer spectral range the optical constants of vanadium films were determined using Kramers-Kronig dispersion relations. Using the optical constants for a wide spectrum the electrical microcharacteristics of vanadium films were determined. Assuming the normal skin effect the electron collision rate and plasma frequency were calculated. The concentration of conduction electrons has been also determined. Making use of knowledge of resistivity in room temperature and in the temperature of liquid helium the electron-photon and electron-impurities collision rate contribution to the effective conduction electron collision rate has been estimated.
