The Quantum Hall Effect in Graphene
El proper dimecres dia 28 de novembre, l'Institut de Nanociència i Nanotecnologia (IN2UB) organitza una conferència sota el títol: The Quantum Hall Effect in Graphene.

Abstract: Graphene, consisting of an isolated single atomic layer of graphite, is an ideal realization of a two-dimensional electron system. Recently, the quantum Hall effect in such a system has been observed and found to differ markedly from the well-studied case of quantum wells in conventional semiconductor interfaces. We show that the Hall conductivity in the two different systems can be explained by means of the same quantum mechanical approach that makes use of linear response theory and Kohn theorem.

La conferència tindrà lloc a la Sala de Graus Eduard Fontserè a les 11:45 hores.
