Increased <i>T</i>_c in Electrolyte‐Gated Cuprates

Abstract

Field-effect transistors built using the high superconducting transition temperature (high-Tc) superconductor YBa2Cu3O7–x as the active conductor and electrolyte as the gate dielectric (see figure) show substantial and relatively robust modulation of conductivity with large increases in Tc of up to 38 K.
