First-principles calculations of phonon transport across a vacuum gap
Takuro Tokunaga, Masao Arai, Kazuaki Kobayashi +5
Phonon transport across a vacuum gap separating intrinsic silicon crystals is predicted via the atomistic Green's function method combined with first-principles calculations of all…
Extreme Near-Field Heat Transfer Between Gold Surfaces
Takuro Tokunaga, Amun Jarzembski, Takuma Shiga +2
Extreme near-field heat transfer between metallic surfaces is a subject of debate as the state-of-the-art theory and experiments are in disagreement on the energy carriers driving…
Ultimate confinement of phonon propagation in silicon nano-crystalline structure
Takafumi Oyake, Lei Feng, Takuma Shiga +3
Temperature-dependent thermal conductivity of epitaxial silicon nano-crystalline (SiNC) structures composed of nanometer-sized grains separated by ultra-thin silicon-oxide (SiO2) f…
Effects of Defects on Thermoelectric Properties of Carbon Nanotubes
Masato Ohnishi, Takuma Shiga, Junichiro Shiomi
Carbon nanotubes (CNTs) have recently attracted attention as materials for flexible thermoelectric devices. To provide theoretical guideline of how defects influence the thermoelec…
Thermal conductivity spectrum calculation from first-principles-based harmonic phonon theory
Takuma Shiga, Daisuke Aketo, Lei Feng +1
In recent years, nanostructuring of dielectric and semiconducting crystals has enhanced controllability of their thermal conductivity. To carry out computational material search fo…
