Graphene is a one-atom-thick planar sheet of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice. The term Graphene was coined as a combination of graphite and the suffix -ene by Hanns-Peter Boehm, who described single-layer carbon foils in 1962. Graphene is most easily visualized as an atomic-scale chicken wire made of carbon atoms and their bonds. The crystalline or "flake" form of graphite consists of many graphene sheets stacked together.

Electronic Structure and Transport Properties of Graphene on Hexagonal Boron Nitride
06 Dec 2018 | Contributor(s):: Shukai Yao, Luis Regalado Bermejo, Alejandro Strachan
Graphene is a zero-bandgap conductor with high carrier mobility. It is desired to search for an opening of band structure of graphene such that this kind of material can be applied in electronic devices. Depositing hexagonal Boron Nitride (h-BN) opens a bandgap in the band structure of...

Modeling of Inter-ribbon Tunneling in Graphene
11 Nov 2016 | | Contributor(s):: Maarten Van de Put, William Gerard Hubert Vandenberghe, Massimo V Fischetti
IWCE presentation. In this paper we investigate the finite-size effect in nano-scaled graphene flakes. Improving on the bulk description, and because the structures are – atomistically speaking – large in size, we use the empirical pseudopotential method.

Symmetry, Dimension, and Spin: Understanding transport in 2D 'phosphorene'
02 Mar 2015 | | Contributor(s):: Ian Appelbaum
Despite its low atomic number and inversion symmetry, recent electronic measurements demonstrate that (group-IV) graphene has a greatly disappointing spin lifetime, corroborated by theory showing strong spin-flip scattering by flexural (out-of-plane) phonons. There exists a class of graphene-like...
