Charge Carrier Localisation in Disordered Graphene Nanoribbons

Abstract

We study the electronic properties of actual-size graphene nanoribbons subjected tosubstitutional disorder particularly with regard to the experimentally observed metal-insulatortransition. Calculating the local, mean and typical density of states, as well as the time-evolutionof the particle density we comment on a possible disorder-induced localisation of charge carriersat and close to the Dirac point within a percolation transition scenario.
