We propose here to evaluate the potential for thermoelectric applications of the niobium oxide dihalide materials. Our study is motivated by the chemical abundance and ease of fabrication of oxyhalides, and the wide range of properties offered by the presence of mixed anions. We consider the case of NbOI2 and find that this material has a relatively large electron affinity, making it likely to be a good n-type semiconductor. We calculate the electronic transport properties and lattice thermal conductivity through the third-order force constants and discuss its potential for thermoelectricity as well as the different conditions required (e.g. thickness, temperature) to achieve good efficiency.
