Abstract

We calculate the conductivity of arbitrarily stacked multilayer graphene sheets within a relaxation time approximation by considering both short-range and long-range impurities. We investigate theoretically the feasibility of identifying the stacking order of these multilayers using transport measurements. For relatively clean samples, the various stacking configurations give over two decades of power-law dependence of the conductivity on carrier density. This arises due to a low density decomposition of the multilayer band structure into a sum of J-chiral Hamiltonians. For dirty samples, the simple power-law relationship no longer holds. Nonetheless, identification of the number of layers and stacking sequence is still possible by careful comparison of experimental data to the results presented here.
