Graphene for Electronics.

Graphene is an allotrope of carbon consisting of a single layer of atoms arranged in a two-dimensional (2D) honeycomb lattice [...

Screening in Graphene: Response to External Static Electric Field and an Image-Potential Problem.

We present a detailed first-principles investigation of the response of a free-standing graphene sheet to an external perpendicular static electric field . The charge density distribution in the vicinity of the graphene monolayer that is caused by was determined using the pseudopotential density-functional theory approach. Different geometries were considered.
