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.
