AI Article Synopsis
- This study examines how monochromatic microwave radiation affects the conductivity of quasi-one-dimensional silver wires, focusing on weak-localization corrections.
- Researchers found that due to enhanced electron cooling, microwave-induced dephasing occurred without excessively heating the electrons, across various power and frequency levels.
- The results align with existing theoretical models, indicating that microwave noise at very low power can influence the dephasing time in low-temperature experiments with one-dimensional wires.
Article Abstract
We report on the effect of monochromatic microwave (MW) radiation on the weak-localization corrections to the conductivity of quasi-one-dimensional silver wires. Because of the improved electron cooling in the wires, the MW-induced dephasing is observed without a concomitant overheating of electrons over wide ranges of the MW power P(MW) and frequency f. The observed dependences of the conductivity and MW-induced dephasing rate on P(MW) and f are in agreement with the theory by Altshuler, Aronov, and Khmelnitsky [Solid State Commun. 39, 619 (1981)]. Our results suggest that in the low-temperature experiments with 1D wires, saturation of the temperature dependence of the dephasing time can be caused by an MW electromagnetic noise with a sub-pW power.
