Electric Field Tuned Dimensional Crossover in Ar-Irradiated SrTiO3
J. H. Ngai, Y. Segal, F. J. Walker +3
We present low temperature magnetoresistance measurements of Ar-irradiated SrTiO3 under an applied electrostatic field. The electric field, applied through a back gate bias, modula…

Tunneling Spectroscopy on c-axis Y{1-x}Ca{x}Ba2Cu3O{7-delta} Thin Films
J. H. Ngai, W. A. Atkinson, J. Y. T. Wei
Scanning tunneling spectroscopy was performed on c-axis Y{1-x}Ca{x}Ba2Cu3O{7-delta} thin films for x= 0, 0.05, 0.15 and 0.20 at 4.2K. The measured spectra show main-gap, sub-gap an…

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…
