Far-field radiative thermal rectification with bulk materials

In this paper, we explore the far-field radiative thermal rectification potential of common materials such as metals,ceramics and doped semi-conductors using thermo-radiative properties extracted from literature. Seventeen different are considered. The coefficient is then calculated for 136 pairs materials; each pair can be used two terminals a diode. A bias 200 K choice value only bound by data availability in Obtained results, highlight new candidate rectification. They also where not negligible should considered with care heat transfer calculations when considering systems subject to comparable these used. Among studied, undoped Indium Arsenide (InAs) shows great promise employed rectification, ratio reaching 96.35% combination other materials. results pave way an optimized design radiation control management devices diodes.
