Abstract

In this paper the heat transport in carbon nanotubes is investigated. When the dimension of the structure is of the order of the de Broglie wave length the transport phenomena must be analyzed within quantum mechanics. In this paper we developed the Dirac type thermal equation. The solution of the equation the temperature fields for electrons can be damped or can oscillate depending on the dynamics of the scattering.
