Fluctuator Model of Memory Dip in Hopping Insulators

Article

Abstract

We show that the non-equilibrium dynamic in two-dimensional hopping insulators close to metal-dielectric transition is sensitive to electric fields confinement inside the sample, which leads to a nearly thermally activated conductance behavior and a strong non-equilibrium conductance response to the gate voltage, including a memory dip in a field dependence of conductance.
