Charge transport in two dimensions limited by strong short-range scatterers : going beyond parabolic dispersion and Born approximation Kailasvuori, Janik Sopik, Bretislav 2014-12-12T10:52:09Z Sopik, Bretislav We investigate the conductivity of charge carriers confined to a two-dimensional system with the nonparabolic dispersion kN with N being an arbitrary natural number. A δ-shaped scattering potential is assumed as the major source of disorder. We employ the exact solution of the Lippmann-Schwinger equation to derive an analytical Boltzmann conductivity formula valid for an arbitrary scattering potential strength. The range of applicability of our analytical results is assessed by a numerical study based on the finite size Kubo formula. We find that for any N>1, the conductivity demonstrates a linear dependence on the carrier concentration in the limit of a strong scattering potential strength. This finding agrees with the conductivity measurements performed recently on chirally stacked multilayer graphene where the lowest two bands are nonparabolic and the adsorbed hydrocarbons might act as strong short-range scatterers.
