Microwave induced nonlocal transport in two-dimensional electron system

TL;DR

This paper reports the observation of microwave-induced nonlocal resistance in 2D electron systems, suggesting the formation of edge state currents stabilized by microwave irradiation, related to oscillations and zero resistance states.

Contribution

It provides experimental evidence for microwave-stabilized edge states causing nonlocal transport in 2D electron systems, a novel insight into microwave-induced phenomena.

Findings

Microwave irradiation induces nonlocal resistance.

Edge state currents are stabilized by nonlinear resonances.

Results relate to microwave-induced oscillations and zero resistance states.

Abstract

We observe microwave induced nonlocal resistance in magnetotransport in single and bilayer electronic systems. The obtained results provide evidence for an edge state current stabilized by microwave irradiation due to nonlinear resonances. Our observation are closely related to microwave induced oscillations and zero resistance states in a two-dimensional (2D) electron system.
