Role of Transversal Phonon Modes in the Specific Heat Capacity of Multi-Wall Carbon Nanotubes
Heat capacity is one of the most important properties of carbon nanotubes for applications in industry and technology. In recent years, experimental and theoretical studies have been carried out to determine the heat capacity of multi-walled carbon nanotubes (MWCNTs). In the present study, the specific heat capacity of MWCNTs was determined in terms of lattice vibrations (phonons) and free electrons. The specific heat of MWCNTs was modeled up to 200 K and deviations observed in Cv–T plots for MWCNTs are explained in terms of transversal phonon modes.
