Observation of Andreev reflection in the c-axis transport of Bi_2Sr_2CaCu_2O_{8+x} single crystals near T_c and search for the preformed-pair state
Hyun-Sik Chang, Hu-Jong Lee, Migaku Oda
We observed an enhancement of the -axis differential conductance around the zero-bias in AuBiSrCaCuO (Bi2212) junctions near the superconducting transitio…
The resistance anomaly in the surface layer of BiSrCaCuO 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 -axis resistance near and below the superconducting transition of the CuO layer in contact wit…
Progressive evolution of tunneling characteristics of in-situ fabricated intrinsic Josephson junctions in Bi_2Sr_2CaCu_2O_{8+delta} single crystals
Yong-Joo Doh, Hu-Jong Lee, Hyun-Sik Chang
Stacks of a few intrinsic tunnel junctions were micro-fabricated on the surface of Bi-2212 single crystals. The number of junctions in a stack was tailored by progressively increas…
Suppressed Superconductivity of the Surface Conduction Layer in BiSrCaCuO Single Crystals Probed by {\it c}-Axis Tunneling Measurements
Nam Kim, Yong Joo Doh, Hyun-Sik Chang +1
We fabricated small-size stacks on the surface of BiSrCaCuO (BSCCO-2212) single crystals with the bulk transition temperature 90 K, each containing…
