Hopping-resolved electron-phonon coupling in bilayer graphene

Abstract

In this paper we investigate the electron-phonon coupling in bilayer graphene, as a paradigmatic case for multilayer graphenes where interlayer hoppings are relevant. Using a frozen-phonon approach within the context of Density Functional Theory (DFT) and using different optical phonon displacements we are able to evaluate quantitatively the electron-phonon coupling ${\alpha }_i$ associated with each hopping term ${\gamma }_i$. This analysis also reveals a simple scaling law between the hopping terms ${\gamma }_i$ and the electron-phonon coupling ${\alpha }_i$ which goes beyond the specific DFT technique employed.
