On the Formation of a Conducting Surface Channel by Ionic-Liquid Gating of an Insulator
Abstract Ionic‐liquid gating has become a popular tool for tuning the charge carrier densities of complex oxides. Among these, the band insulator SrTiO 3 is one of the most extensively studied materials. While experiments have succeeded in inducing (super)conductivity, the process by which ionic‐liquid gating turns this insulator into a …
