The resistance anomaly in the surface layer of Bi${}_2$Sr${}_2$CaCu${}_2$O${}_{8+x}$ single crystals under radio-frequency irradiation

Nam Kim, Hyun-Sik Chang, Hu-Jong Lee +1

We observed that radio-frequency (rf) irradiation significantly enhances the $c$-axis resistance near and below the superconducting transition of the CuO${}_2$ layer in contact wit…
