Gap parameter effect on thermal transport of doped armchair gapped graphene nanoribbon structure

Abstract

We address the thermal conductivity of armchair graphene nanoribbon within tight binding model Hamiltonian. The possible effects of gap parameter, ribbon width and chemical potential on thermal conductivity are investigated. Green's function approach has been employed in order to calculate thermal conductivity of the system. We have also found the temperature dependence of the thermal conductivity for various ribbon widths and chemical potentials. Our results show a peak appears in temperature dependence of thermal conductivity for each value of chemical potential and ribbon width.
