In the past two years, it has been demonstrated that applied electric fields can be used to modulate significantly the normal state resistivity, the critical temperature and the critical current density of high-Tc films. Whereas earlier publications focussed on experimental aspects of high-Tc field effects, this contribution will discuss the conditions that are required to induce superconductivity on the surface of insulators. In addition, evaluations for performance limits of potential high-Tc field effect devices will be presented.
