Kechedzhi, K. and McCann, Edward and Falko, Vladimir and Suzuura, H. and Ando, T. and Altshuler, B. L. (2007) Weak localization in monolayer and bilayer graphene. European Physical Journal - Special Topics, 148 (1). pp. 39-54. ISSN 1951-6355Full text not available from this repository.
We describe the weak localization correction to conductivity in ultra-thin graphene films, taking into account disorder scattering and the influence of trigonal warping of the Fermi surface. A possible manifestation of the chiral nature of electrons in the localization properties is hampered by trigonal warping, resulting in a suppression of the weak anti-localization effect in monolayer graphene and of weak localization in bilayer graphene. Intervalley scattering due to atomically sharp scatterers in a realistic graphene sheet or by edges in a narrow wire tends to restore weak localization resulting in negative magnetoresistance in both materials.
