Abstract
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 Bi(5+) oxide.Entities:
