Electronic transmission in Graphene suppressed by interlayer interference

TL;DR

This paper demonstrates that electronic transmission in graphene monolayers can be suppressed by interlayer interference caused by nanoribbons, with potential applications in nano-electronic device control.

Contribution

It introduces a novel method of controlling graphene's electronic transmission through nanoribbon-induced interference effects, expanding the understanding of interlayer interactions.

Findings

Transmission reduction depends on nanoribbon width and energy.

Interference explains the suppression of electron flow.

Multiple nanoribbons can be combined for enhanced control.

Abstract

We investigate electronic transport property of a graphene monolayer covered by a graphene nanoribbon. We demonstrate that electronic transmission of a monolayer can be reduced when covered by a nanoribbon. The transmission reduction occurs at different energies determined by the width of nanoribbon. We explain the transmission reduction by using interference between wavefunctions in the monolayer and the nanoribbon. Furthermore, we show the transmission reduction of a monolayer is combinable when covered by more than one nanoribbon and propose a concept of "combination of control" for nano-application design.
