Abstract

A high-T_c field-effect transistor-like structure (SuFET) was made rhich consisted of an ultrathin YBa₂Cu₃O_7-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 J_c 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-T_c superconductors.
