Anomalous Parallel Field Negative Magnetoresistance in Ultrathin Films Near the Superconductor-Insulator Transition
Kevin A. Parendo, L. M. Hernandez, A. Bhattacharya +1
A parallel field negative magnetoresistance has been found in quench-condensed ultrathin films of amorphous bismuth in the immediate vicinity of the thickness-tuned superconductor-…
Low Temperature Metallic State of Ultrathin Films of Bismuth
L. M. Hernandez, Kevin A. Parendo, A. M. Goldman
Measurements of resistance vs. temperature have been carried out on a sequence of quench-condensed ultrathin films of amorphous bismuth (a-Bi). The resistance below about 0.1K was…
Bottom-loading dilution refrigerator with ultra-high vacuum deposition capability
L. M. Hernandez, A. M. Goldman
A Kelvinox 400 dilution refrigerator with the ability to load samples onto the mixing chamber from the bottom of the cryostat has been combined with an ultrahigh-vacuum (UHV) depos…
Evidence of Collective Charge Behavior in the Insulating State of Ultrathin Films of Superconducting Metals
C. Christiansen, L. M. Hernandez, A. M. Goldman
Nonlinear I-V characteristics have been observed in insulating quench-condensed films which are locally superconducting. We suggest an interpretation in terms of the enhancement of…
Parallel Magnetic Field Induced Glass-Like Behavior of Disordered Ultrathin Films
L. M. Hernandez, A. Bhattacharya, K. A. Parendo +1
Dramatic glass-like behavior involving nonexponential relaxation of in-plane electrical conduction, has been induced in quench-condensed ultrathin amorphous Bi films by the applica…
