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…
Probing Near-Field Thermal Emission of Localized Surface Phonons from Silicon Carbide Nanopillars
Saman Zare, Ramin Pouria, Philippe K. Chow +3
Thermal emission of localized surface phonons (LSPhs) from nanostructures of polaritonic materials is a promising mechanism for tuning the spectrum of near-field thermal radiation.…
