We review the recently-developed theory of weak localization in monolayer
and bilayer graphene. For high-density monolayer graphene and for
any-density bilayers, the dominant factor affecting weak localization
properties is trigonal warping of graphene bands, which reflects
asymmetry of the carrier dispersion with respect to the center of
the corresponding valley. The suppression of weak localization by
trigonal warping is accompanied by a similar effect caused by random-bond
disorder (due to bending of a graphene sheet) and by dislocation/antidislocation
pairs. As a result, weak localization in graphene can be observed
only in samples with sufficiently strong intervalley scattering,
which is reflected by a characteristic form of negative magnetoresistance
in graphene-based structures.
