THERMAL CONDUCTIVITY OF GRAPHENE FOR COHERENT AND NON-COHERENT HOLE –ELECTRON'S STATES
Journal Title: Journal of Science And Arts - Year 2013, Vol 23, Issue 2
Abstract
In this thesis, we investigate the thermal transport properties of graphene using the Boltzmann approximation. Based on the analytical solution of Boltzmann equation for coherent and non-coherent electron-hole states, the minimum electrical and thermal conductivities are studied. We solve the Boltzmann equation in the chirality basis by considering off-diagonal elements of the distribution function due to the electron-hole coherency effect and calculate the thermal transport properties of graphene. Finally, we obtain the thermal coefficients as functions of temperature. Our results show that the thermal conductivity in non-coherent electron-hole state has a linear behavior at low temperature.
