Andreev reflection spectroscopy on BiX (X = Se, Te) topological insulators: Implications for the c-axis superconducting proximity effect
C. R. Granstrom, I. Fridman, H. -C. Lei +2
Using Andreev reflection (AR) as an experimental gauge of the superconducting proximity effect (PE), we assess the topological purity of the superconductivity that is induced by th…
Andreev nanoprobe of half-metallic CrO films using superconducting cuprate tips
C. S. Turel, I. J. Guilaran, P. Xiong +1
Superconducting tips of YBaCuO were used to perform point-contact Andreev reflection spectroscopy on half-metallic CrO thin films. At 4.2K, strong suppre…
Local tunneling probe of (110) Y_0.95Ca_0.05Ba_2Cu_3O_7-delta thin films in a magnetic field
J. H. Ngai, R. Beck, G. Leibovitch +2
Scanning tunneling spectroscopy was performed on (110)-oriented thin films of Ca-overdoped YCaBaCuO at 4.2K, to probe the local evolution of Andre…
Selective epitaxial growth of sub-micron complex oxide structures by amorphous SrTiO3
P. Morales, M. DiCiano, J. Y. T. Wei
A chemical-free technique for fabricating submicron complex oxide structures has been developed based on selective epitaxial growth. The crystallinity and hence the conductivity of…
Suppression of low-energy Andreev states by a supercurrent in YBa_2Cu_3O_7-delta
J. Ngai, P. Morales, J. Y. T. Wei
We report a coherence-length scale phenomenon related to how the high-Tc order parameter (OP) evolves under a directly-applied supercurrent. Scanning tunneling spectroscopy was per…
