Dynamical creation of gap in the monolayer graphene

TL;DR

This paper demonstrates that the zero-gap electronic structure of monolayer graphene is unstable due to electron-phonon interactions causing dynamic symmetry breaking.

Contribution

It introduces a mechanism for gap creation in monolayer graphene through dynamic symmetry violation induced by electron-phonon interactions.

Findings

Zero-gap bands are unstable under electron-phonon interactions.

Dynamic symmetry breaking can induce a band gap in graphene.

Potential implications for electronic device engineering.

Abstract

The zero gap electronic bands in the monolayer graphene are shown to be unstable relative to the dynamic symmetry violation due to the electron-phonon interaction.
