SUMMARY

Thermal transport at the interfaces of low-dimensional carbon nano-structures such as carbon nanotube (CNT) and graphene interfaces become very important in their nano-electronic devices. A fundamental understanding of phonon transport at these interfaces is required for the energy efficient design of CNTs and graphene devices. This work is aimed to investigate the phonon interactions and heat dissipation at the interfaces involving CNTs and graphene, to predict the phonon transmission and thermal boundary conductance (TBC) at graphene/metal interfaces, and to analyze the electron-phonon coupling at graphene/metal nanostructures. This study is carried out using atomistic modeling techniques including MD simulations, AGF calculations, DFT calculations, and BTE simulations. The work showed the relation between the dominated heat dissipation mechanism and the important physical and structural parameters, which is critical for the thermal management design of CNT/graphene nanoelectronic devices.
