Ultrathin Stable Ohmic Contacts for High-Temperature Operation of -GaO Devices
William A. Callahan, Edwin Supple, David Ginley +4
Beta gallium oxide (-GaO) shows significant promise in the high-temperature, high-power, and sensing electronics applications. However, long-term stable metallization la…
Coupled Charge and Radiation Transport Processes in Thermophotovoltaic and Thermoradiative Cells
William A. Callahan, Dudong Feng, Zhuomin M. Zhang +3
Accurate modeling of charge transport and both thermal and luminescent radiation is crucial to the understanding and design of radiative thermal energy converters. Charge carrier d…
Solar Thermoradiative-Photovoltaic Energy Conversion
Eric J. Tervo, William A. Callahan, Eric S. Toberer +2
We propose a solar thermal energy conversion system consisting of a solar absorber, a thermoradiative cell or negative illumination photodiode, and a photovoltaic cell. Because it…
