Enhancement of far-field thermal emission via polaritonic cavity modes
Maelie Coral, Jose Ordonez-Miranda, Georges Hamaoui +5
Controlling thermal emission is crucial for applications involving thermophotovoltaics, thermal sensing, imaging, and camouflage. While prior studies focused on the emission of the…
Enhanced Near-Field Thermal Radiation Driven by Multiple Corner and Edge Modes in Subwavelength Square Nanowires
Jose Ordonez-Miranda, Minggang Luo, Michele Diego +4
We demonstrate that the near-field thermal radiation between subwavelength SiC nanowires with square cross sections is dominated by multiple corner and edge resonances rather than…
Beam-Offset Thermoreflectance with Bayesian Optimization to Measure the Anisotropic Thermal Properties of Semiconductor Superlattices
A. Chatterjee, N. Spitzer, T. Kruck +5
The directional nature of heat conduction in semiconductor superlattices--marked by significant differences between in-plane and cross-plane pathways--poses substantial challenges…
Ultra-High-Temperature Vacuum Prober for Electrical and Thermal Measurements
Laurent Jalabert, Jose Ordonez-Miranda, Yunhui Wu +4
We develop an ultra-high-temperature vacuum probe station (UHT-VPS) featuring a sample holder heated by thermal radiation from a silicon carbide heater. This contactless configurat…
Using oxides to compute with heat
Guillaume F. Nataf, Sebastian Volz, Jose Ordonez-Miranda +3
One of the most innovative possibilities offered by oxides is the use of heat currents for computational purposes. Towards this goal, phase-change oxides, including ferroelectrics,…
