Novel Transport Mechanism for Interacting Electrons in Disordered Systems: Variable-Range Resonant Tunneling

TL;DR

This paper proposes a new transport mechanism for electrons in disordered systems, where electrons move through quantum resonant tunneling facilitated by environmental electron hops, explaining phononless hopping conduction.

Contribution

It introduces a novel resonant tunneling model for electron transport in disordered systems, expanding understanding of conduction mechanisms without phonon involvement.

Findings

Resonant tunneling explains phononless hopping conduction.

Fast electron hops induce resonance between localized states.

The model aligns with recent experimental observations.

Abstract

To interpret recent experimental observations of the phononless hopping conduction, we suggest a novel transport mechanism according to which the current-carrying single electrons move via quantum resonant tunneling between localized states brought into resonance by fast electron hops in their environment.
