Hot-carrier thermophotovoltaic systems
Kartika N. Nimje, Maxime Giteau, Georgia T. Papadakis
A thermophotovoltaic (TPV) energy converter harnesses thermal photons emitted by a hot body and converts them to electricity. When the radiative heat exchange between the emitter a…
Thermodynamic performance bounds for radiative heat engines
Maxime Giteau, Michela F. Picardi, Georgia T. Papadakis
Heat engines cannot generally operate at maximum power and efficiency, imposing a trade-off between the two. Here, we highlight the exact nature of this trade-off for engines that…
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…
Experimental demonstration of tunable graphene hyperbolic metamaterial
Jeremy Brouillet, Georgia T. Papadakis, Harry A. Atwater
Tuning the macroscopic dielectric response on demand holds potential for actively tunable metaphotonics and optical devices. In recent years, graphene has been extensively investig…
Gate-tunable near-field heat transfer
Georgia T. Papadakis, Bo Zhao, Siddharth Buddhiraju +1
Active control over the flow of heat in the near-field holds promise for nanoscale thermal management, with applications in refrigeration, thermophotovoltaics, and thermal circuitr…
