Infrared Phonon Thermoreflectance in Polar Dielectrics
Saman Zare, William D. Hutchins, Daniel Hirt +2
In this work, we investigate dielectric materials for thermoreflectance-based thermal sensing by extracting key optical parameters using temperature-dependent spectroscopic ellipso…

Interfacial Heat Transport via Evanescent Radiation by Hot Electrons
William D. Hutchins, Saman Zare, Mehran Habibzadeh +2
We predict an additional thermal transport pathway across metal/non-metal interfaces with large electron-phonon non-equilibrium via evanescent radiative heat transfer. In such syst…

Ultrafast evanescent heat transfer across solid interfaces via hyperbolic phonon polaritons in hexagonal boron nitride
William Hutchins, John A. Tomko, Dan M. Hirt +10
The efficiency of phonon-mediated heat transport is limited by the intrinsic atomistic properties of materials, seemingly providing an upper limit to heat transfer in materials and…
