Abstract
The mechanisms of dark- and photoconductivity in ZnO:Li films are investigated. The obtained results are interpreted on the basis of hopping mechanism of charge carriers transport for the dark conductivity and the hopping or drift mechanism for the photoconductivity depending on the energy of an exciting photon. For photons with the energy more than the forbidden band gap the drift mechanism of carriers transport takes place, while for photons with the energy less than the forbidden band gap the hopping mechanism takes place.
