Abstract
We calculate electronic charge and heat transport in tubular nanowires generated by a temperature gradient or a chemical potential bias. These nanowires correspond to semiconductor core-shell nanowires with insulating (undoped) core and conductive (doped) shell, such that the conduction takes place only in the shell. The cross section of such nanowires is typically polygonal. We study the influence of the cross section shape and shell thickness on the electric and heat conduction of the shell. We use the Landauer-Büttiker approach to calculate the electric and heat currents as a non-linear function of temperature and chemical potential bias beyond the linear regime.
