EFFECT OF AN AC ELECTRIC-FIELD ON WEAK ELECTRON LOCALIZATION IN BI FILMS

We have studied the effects of weak localization and electron-electron interaction in conductivity of Bi films at temperatures between 1.1 a nd 4.2 K in high-frequency electric field (similar or equal to 9.4 GHz ). The experiments are carried out under conditions of no appreciable overheating of electrons due to microwave radiation. The data obtained permit to examine the influence of temperature on quantum corrections Delta sigma(Omega) in high-frequency electric field more comprehensiv ely and reliably than in earlier works. The experimental dependences D elta sigma(Omega,T) are found to be in good agreement with the known t heoretical models.
