Thermal Transport Study in a Strained Carbon Nanotube and Graphene Junction Using Phonon Wavepacket Analysis

Graphene and Graphene Multilayers: Phonon Thermal Transport

In this entry, we review thermal properties of graphene and multilayer graphene and discuss in detail the optothermal Raman technique developed for the thermal conductivity measurements. We also outline different theoretical approaches used for the description of phonon transport in graphene and provide comparison with the available experimental thermal conductivity data.

Phonon Scattering and Electron Transport in Single Wall Carbon Nanotube

Single-walled carbon nanotube (SWCNTs) can be thought of as graphene a single graphene sheet wrapped up to form a one-atom-thick cylinders. CNTs were discovered by Iijima [1] in 1991, since then the excellent charge transport properties of CNTs have been of great inter‐ est, for its great potential applications in nanoelectronics, such as high-speed field-effect transistors (FETs) [2, 3], singl...

Zone-Boundary Phonon in Graphene and Nanotube

Zone-boundary phonons are described in a valence-force-field model and then converted into a continuum model. Only a mode with the highest frequency corresponding to a Kekulé-type distortion gives rise to inter-valley electron scattering between K and K’ points. An effective Hamiltonian for this interaction is obtained and used for the estimation of inter-valley scattering in graphene and nanot...
