  In this paper, we explore the far-field radiative thermal rectification
potential of common materials such as metals, dielectrics and doped
semi-conductors using radiative and thermo-radiative properties extracted from
literature. Ten different materials are considered. The rectification
coefficient is then calculated for 44 pairs of materials; each pair can be used
for the two terminals of a radiative thermal diode. A thermal bias of 200 K is
considered. The choice of materials and thermal bias value is only bound by
data availability in literature. Obtained results, highlight new candidate
materials for far-field radiative thermal rectification. They also highlight
materials where thermal rectification is not negligible and should be
considered with care in heat transfer calculations when considering systems
subject to a comparable thermal bias and where these materials are used. Among
the materials studied, undoped Indium Arsenide (InAs) shows great promise to be
employed for thermal rectification, with a thermal rectification ratio reaching
90.5% in combination with other materials. Obtained results pave the way for an
optimized design of thermal radiation control and management devices such as
thermal diodes.
