Analytical and numerical solutions to the non-diffusive Stefan problem
Matthew Van Ham, Minghan Xu, Samuel Huberman
In this work, the Maxwell--Cattaneo--Vernotte (MCV) equation is used to model the one-dimensional hyperbolic Stefan problem in the limit of a small Stefan number (Ste 1). The…
Probing carrier and phonon transport in semiconductors all at once through frequency-domain photo-reflectance
Qichen Song, Sorren Warkander, Samuel C. Huberman
Semiconductor devices favor high carrier mobility for reduced Joule heating and high thermal conductivity for rapid heat dissipation. The ability to accurately characterize the mot…
Ultrafast Electron Diffuse Scattering as a Tool for Studying Phonon Transport: Phonon Hydrodynamics and Second Sound Oscillations
Laurenz Kremeyer, Tristan L. Britt, Bradley J. Siwick +1
Hydrodynamic phonon transport phenomena, like second sound, have been observed in liquid Helium more than 50 years ago. More recently second sound has been observed in graphite at…
On the question of second sound in germanium: A theoretical viewpoint
Samuel Huberman, Chuang Zhang, Jamal Abou Haibeh
We revisit the recent work from Beardo et al. \cite{beardo2021observation} wherein the observation of second sound in germanium is claimed. We review the requirements imposed on th…
A note on a unified theory of thermal transport in crystals and disordered solids
Samuel Huberman
We propose an extension to the original result derived by Simoncelli et al. (https://doi.org/10.1038/s41567-019-0520-x) to encompass the effects of a space and time dependent heat…
On the emergence of heat waves in the transient thermal grating geometry
Chuang Zhang, Samuel Huberman, Lei Wu
The propagation of heat in the transient thermal grating geometry is studied based on phonon Boltzmann transport equation (BTE) in different phonon transport regimes. Our analytica…
