PY 1991 BP 629 EP 630 VL 169 IS 1-4 DI 10.1016/0921-4526(91)90360-Q DE impure superconductors AB Transition from microwave enhancement of supercurrent to superconductivity suppression is investigated in impure superconductors. It is demonstrated that frequency range of enhancement effect narrows with the decrease of electron mean free path, ℓ, and at ℓ⩽1nm electron heating is observed in the whole frequency range. Dependences of frequency boundaries on ℓ are explained by taking into account strong electron-electron interaction in impure metals. ER
