Epitaxial growth and semiconductor properties of NiGa2O4 spinel for Ga2O3/NiO interfaces
Kingsley Egbo, Emily M. Garrity, Shivashree Shivamade Gowda +8
Unintentionally formed interfacial layers are ubiquitous in semiconductor devices that operate at extreme conditions. However, these layers' structure and properties often remain u…
Unveiling Phonon Contributions to Thermal Transport and the Failure of the Wiedemann-Franz Law in Ruthenium and Tungsten Thin Films
Md. Rafiqul Islam, Pravin Karna, Niraj Bhatt +12
Thermal transport in nanoscale interconnects is dominated by intricate electron-phonon interactions and microstructural influences. As copper faces limitations at the nanoscale, tu…
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…
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…
Experimental observation of ballistic to diffusive transition in AlN thin films
Md Shafkat Bin Hoque, Michael E. Liao, Saman Zare +10
Bulk AlN possesses high thermal conductivity due to long phonon mean-free-paths, high group velocity, and long lifetimes. However, the thermal transport scenario becomes very diffe…
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…
Disorder controlled sound speed and thermal conductivity of hybrid metalcone films
Md Shafkat Bin Hoque, Rachel A. Nye, Saman Zare +6
The multifaceted applications of polymers are often limited by their thermal conductivity. Therefore, understanding the mechanisms of thermal transport in polymers is of vital inte…
