Electric field control of superconducting fluctuations and quasiparticle interference at oxide interfaces

Graham Kimbell, Ulderico Filippozzi, Stefano Gariglio +4

We investigate tunable superconducting transitions in (111)${\mathrm{LaAlO}}_3/{\mathrm{KTaO}}_3$ field-effect devices. Large increases in conductivity, associated with superconducting…
