摘要
Disorder effects strongly influence the transport properties of graphene-based nanodevices even to the point of Anderson localization. Focusing on the local density of states and its distribution function, we analyze the localization properties of actual size graphene nanoribbons. In particular, we determine the time evolution and localization length of the single-particle wave function in dependence on the ribbon extension and edge geometry as well as on the disorder type and strength.
