Electric field effect on superconducting YBa2Cu3O7-δ films

View publication


MISFET-type structures have been developed that allow the application of electric fields larger than 4 × 106 V/cm into 100 Å thick, superconducting YBa2Cu3O7-δ channel layers. With these structures, t he carrier density and the electrical resistivity of YBa2Cu3O7-δ can be modified in the percent range by gate voltages of 50 V. © 1991.
