Abstract

A high-Tc field-effect transistor-like structure (SuFET) was made rhich consisted of an ultrathin YBa2Cu3O7-x (YBCO) film, a dielectric SrTiO3 layer, and a gold gate electrode. The use of ultrathin films of a few unit cells thickness and an epitaxially grown dielectric layer allowed a relative change in the areal carrier density of YBCO in excess of 20%. A comparable amount of modulation was obtained in normal state resistivity and T c. The Jc of the channel layer was changed by approximately 90% when a gate voltage was applied, showing the promise to build a field effect device using high-Tc superconductors.
