We have seen that some PSs have been studied for their optoelectronic properties, but only very few materials have been reported in more than a single publication. In addition, work has almost only focused on thiophosphates. Does the PS material family warrant a broader, rational search for new semiconductors? If so, where should we search? To help answer these questions, we examine selected properties of all the ternary PSs present on MP and predicted to be thermodynamically stable by DFT. The examined properties are band gap (Fig. ), structural dimensionality (Fig. ), and effective masses (Fig. ). When specific materials are discussed, reference is made to their Materials Project ID.
