Quantifying Surface Roughness Effects on Phonon Transport in Silicon Nanowires
A good power law correlation w/ surface roughness indicates a new realm of phonon scattering from rough interfaces, which restricts phonon transport below the Casimir limit.
Temperature-Gated Thermal Rectifier for Active Heat Flow Control
A temperature-gated thermal rectification using vanadium dioxide beams was observed in which the environmental temperature actively modulates asymmetric heat flow.
Crossover from incoherent to coherent phonon scattering in epitaxial oxide superlattices
Phonon scattering in epitaxial oxide superlattices, manifested by a minimum in lattice thermal conductivity as a function of interface density, indicates crossover from diffuse (particle-like) to specular (wave-like) phonon scattering.
