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 the conductivity of Bi films at temperatures between 1 .1 and 4.2 K in the presence of a high-frequency electric field (simil ar or equal to 9.4 GHz).The experiments were carried out under conditi ons of no appreciable overheating of electrons due to a microwave radi ation. The data obtained permit us to examine the influence of tempera ture on quantum corrections Delta sigma(Omega) at high-frequency elect ric field more comprehensively and reliably than in earlier works. The experimental dependences Delta sigma(Omega, T) are found to be in goo d agreement with the known theoretical models.
