Characterization of polycrystalline samples of the trirutile oxides ZnBi2O6 and MgBi2O6 reveals temperature independent conductivity (0.4 and 0.01 S cm−1), a negative Seebeck coefficient (−0.035 and −0.025 mV K−1), and an optical band gap that falls at the low energy end of visible region (1.7 and 1.8 eV), this combination of attributes, indicating that these compounds are degenerate n-type semiconductors, has not previously been observed in a Bi5+ oxide.
