Nonequilibrium Green's Function Approach to Phonon Transport in Defective Carbon Nanotubes
Takahiro Yamamoto, Kazuyuki Watanabe
We have developed a new theoretical formalism for phonon transport in nanostructures using the nonequilibrium phonon Green's function technique and have applied it to thermal condu…
Electronic Transport in Fullerene C20 Bridge Assisted by Molecular Vibrations
Takahiro Yamamoto, Kazuyuki Watanabe, Satoshi Watanabe
The effect of molecular vibrations on electronic transport is investigated with the smallest fullerene C20 bridge, utilizing the Keldysh nonequilibrium Green's function techniques…
Field emission mechanisms of graphitic nanostructures
Masaaki Araidai, Yasuhiro Nakamura, Kazuyuki Watanabe
Field emission (FE) and the electronic-states origin of graphitic nanostructures were investigated by first-principles calculations based on time-dependent density-functional theor…
Empirical potential study of phonon transport in graphitic ribbon
Takahiro Yamamoto, Kazuaki Mii, Kazuyuki Watanabe
The thermal properties of graphitic ribbon are investigated based on Brenner's empirical potential. The reliability and usefulness of the empirical potential to address the thermal…
Universal Features of Quantized Thermal Conductance of Carbon Nanotubes
Takahiro Yamamoto, Satoshi Watanabe, Kazuyuki Watanabe
The universal features of quantized thermal conductance of carbon nanotubes (CNTs) are revealed through theoretical analysis based on the Landauer theory of heat transport. The pho…
