摘要：

The effect of electric field on ultrathin YBa2Cu3O7-delta grain boundary Josephson junctions has been investigated. A conventional metal insulator superconductor field effect transistor structure consisting of a Pr0.55Y0.45Ba2Cu3O7-delta/YBa2Cu3O7-delta bilayer channel, a crystalline SrTiO3 dielectric, and an Au gate electrode is deposited on a SrTiO3 bicrystal substrate. At high bias current (I(bias)much greater than I-c) the observed effect is compatible with a parallel resistor model using a value close to the bulk charge carrier density of YBa2Cu3O7-delta. At low bias current (I(bias)greater than or equal to I-c) an enhanced field effect not compatible with a parallel resistor model is observed. This enhanced effect is related to the field dependent dielectric properties of the crystalline SrTiO3 insulation layer. (C) 1995 American Institute of Physics.
