  In this paper heat transport in carbon nanotubes is investigated. When the
dimension of the structure is of the order of the de Broglie wave length
transport phenomena must be analysed by quantum mechanics. In this paper we
derived the Dirac type thermal equation .The solution of the equation for the
temperature fields for electrons can either be damped or can oscillate
depending on the dynamics of the scattering. Key words: Carbon nanotubes,
ultrashort laser pulses, Dirac thermal equation, temperature fields.
