Electrostatic Tuning of the Superconductor-Insulator Transition in Two Dimensions
Kevin A. Parendo, K. H. Sarwa B. Tan, A. Bhattacharya +3
Superconductivity has been induced in insulating ultra-thin films of amorphous bismuth using the electric field effect. The screening of electron-electron interaction was found to…

Ambipolar gate effect and low temperature magnetoresistance of ultrathin La0.8Ca0.2MnO3 Films
M. Eblen-Zayas, A. Bhattacharya, N. E. Staley +2
Ultrathin La0.8Ca0.2MnO3 films have been measured in a field-effect geometry. The electric field due to the gate produces a large ambipolar decrease in resistance at low temperatur…
