Ionic liquid gating of strontium titanate nanostructures

ORAL

Abstract

We present electronic transport measurements of two-dimensional electron systems (2DES) induced on strontium titanate surfaces. Using a combination of ionic liquid gates and nanopatterned metallic gates, we demonstrate the ability to isolate a nanoscale puddle of the 2DES and modulate its conductance over several orders of magnitude. Finally, we discuss the apparently gate-tunable superconducting behavior in these devices.
