Transport Length Scales in Disordered Graphene-Based Materials: Strong Localization Regimes and Dimensionality Effects
Transport Length Scales in Disordered Graphene-Based Materials: Strong Localization Regimes and Dimensionality Effects
We report on a numerical study of quantum transport in disordered two dimensional graphene and graphene nanoribbons. By using the Kubo and the Landauer approaches, transport length scales in the diffusive (mean free path, charge mobilities) and localized regimes (localization lengths) are computed, assuming a short range disorder (Anderson-type).
