Weiss oscillations in graphene with a modulated height profile

TL;DR

This paper investigates how height modulations and strain-induced potentials in graphene lead to Weiss oscillations in magnetoconductivity, proposing experimental setups to observe these effects.

Contribution

It demonstrates that substrate-induced height modulations and parallel magnetic fields can produce Weiss oscillations in graphene's magnetotransport properties, revealing new ways to control electronic behavior.

Findings

Height modulations induce scalar and vector potentials causing Weiss oscillations.

Parallel magnetic fields can replicate effects of height modulations.

Experimental parameters for observing these effects are discussed.

Abstract

We study the electronic transport properties of a monolayer graphene with a one-dimensional modulated height profile caused, for instance, by substrate ondulations. We show that the combined effect of the resulting strain fields induce modulated scalar and vector potentials that give rise to Weiss oscillations in the magnetoconductivity. We also find that similar effects can be obtained by applying a parallel magnetic field to the graphene-substrate interface. The parameters of an experimental set-up for a physical realization of these findings in graphene systems are discussed.
