Magnetism and structure at a vacancy in graphene

Mesoscale and Nanoscale Physics 2008-07-11 v1 Materials Science

Abstract

The electronic structure, bonding and magnetism in graphene containing vacancies are studied using density-functional methods. The single-vacancy graphene ground state is spin polarized and structurally flat. The unpolarized state is non planar only for finite segments. Systems containing periodic arrays of vacancies displays magnetic transitions and metal-insulator transitions.
