Descrição

The graphene lattice: temperature effects and distorsions

Annalisa Fasolino (Radboud University Nijmegen, The Netherlands)

The perfect hexagonal lattice of graphene is not only the origin of its unique electronic properties but also an ideal realization of a truly two-dimensional crystal with not less exceptional behaviour. Graphene has a rippled structure at any finite temperature, negative thermal expansion, a peculiar phonon spectrum and melts in an unusual way. These and other lattice properties, like defects and edges, calculated by accurate atomistic simulations will be briefly discussed.
