Abstract
We develop a theory for the temperature and density dependence of phonon-limited resistivity in bilayer and multilayer graphene and compare with the corresponding monolayer result. For the unscreened case, we find with in the high-temperature limit, and with in the low-temperature Bloch-Grüneisen limit, where and are Fermi velocity and Fermi wave vector, respectively. If screening effects are taken into account, in the high-temperature limit with a renormalized , which is a function of the screening length, and in the low-temperature limit with but independent of . These relations hold in general with and a chiral factor in determined by the specific chiral band structure for a given density.
