Measurements and Numerical Calculations of Thermal Conductivity to Evaluate the Quality of β-Gallium Oxide Thin Films Grown on Sapphire and Silicon Carbide by Molecular Beam Epitaxy
Diego Vaca, Matthew Barry, Luke Yates +8
We report a method to obtain insights into lower thermal conductivity of β-Ga2O3 thin films grown by molecular beam epitaxy (MBE) on c-plane sapphire and 4H-SiC substrates. We comp…
Ultra-Thin Absorber based on Phase Change Metamaterial Superlattice
Michael A. Mastro, Virginia D. Wheeler
In this paper, a superlattice VO2/SiO2 metamaterial on a lossy substrate is designed to create a near perfect absorber with tunability across the infrared spectrum. We selected VO2…
Experimental Demonstration of Dynamic Thermal Regulation using Vanadium Dioxide Thin Films
Ahmed M. Morsy, Michael T. Barako, Vladan Jankovic +6
We present an experimental demonstration of passive, dynamic thermal regulation in a solid-state system with temperature-dependent thermal emissivity switching. We achieve this eff…
Integration of Atomic Layer Epitaxy Crystalline Ga2O3 on Diamond for Thermal Management
Zhe Cheng, Virginia D. Wheeler, Tingyu Bai +6
Ga2O3 has attracted great attention for electronic device applications due to its ultra-wide bandgap, high breakdown electric field, and large-area affordable substrates grown from…
Hybrid Longitudinal-Transverse Phonon Polaritons
Christopher R. Gubbin, Rodrigo Berté, Michael A. Meeker +6
We demonstrate how to exploit long-cell polytypes of silicon carbide to achieve strong coupling between transverse phonon polaritons and zone folded longitudinal optical phonons. T…
Water affinity to epitaxial graphene: the impact of layer thickness
Cristina E. Giusca, Vishal Panchal, Martin Munz +5
The sensitivity to water of epitaxial graphene is examined in this study.
