Detailed characterization is essential to understand the potential applications of novel materials. However, experimental characterization can be challenging due to the vast chemical and physical spaces, as well as the specific conditions required for certain techniques. Computational high-throughput methods can overcome these challenges. In this work, the transport and thermoelectric properties of the recently synthesized bulk BiN are explored, including the effects of temperature, pressure, carrier concentration, polymorphism and polycrystalline grain size. We find that the band structure is strongly dependent on pressure and the polymorph studied. Both polymorphs exhibit low thermal conductivity at 0 GPa, which rapidly increases when pressure is applied. Electronic transport properties can be finely tuned based on the effects of pressure and polymorph type on the band gap, carrier mobilities, and presence of secondary pockets. The thermoelectric figure of merit can reach values around 0.85 for both p- and n-type BiN if the power factor and lattice thermal conductivity are optimized at 600 K, making this material competitive with other well-known thermoelectric families, such as Bi2Te3 or PbX, in the low-to-medium temperature range.<\/p>\n<p>&nbsp;<\/p>\n<p><a href=\"https:\/\/pubs.rsc.org\/en\/content\/articlelanding\/2025\/ta\/d4ta05891g\">https:\/\/pubs.rsc.org\/en\/content\/articlelanding\/2025\/ta\/d4ta05891g<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Abstract Materials discovery extends beyond the synthesis of new compounds.
