dcterms:description
Thermoelectric polycrystalline chromium oxynitride CrO0.09(3)N0.90(7)(with cubic symmetry and space group Fm-3m) samples were successfully prepared by thermal ammonolysis of chromium oxide. This potential n-type thermoelectric material shows a temperature dependence of the Seebeck coefficient (S = -48 μ V K-1 at 300 K)that is typical for degenerate semiconductors; the electrical resistivity(ρ300 2.8 mΩ cm), however, is highly influenced by the grain boundaries and low density (60%) of the sample. The material exhibits a clear antiferromagnetic–paramagnetic transition simultaneously with an orthorhombic–cubic structural transition at TN = 262 K.The magnetic transition affected the material’s thermal conductivity, electrical resistivity, Seebeck coefficient, magnetic moment and specific heat.
