摘要：

The electrical conductivity and Seebeck coefficient for TiO2 doped with varying amounts of MnO2 have been measured over the temperature range of 900 degrees-1100 degrees C. The Hall coefficient was also measured over the temperature range of 300 degrees-500 degrees C. The electrical conductivity and carrier density were found to decrease initially, go through a minimum at approximately x = 0.0001-0.001, and then increase with increasing content of MnO. For dopant levels above 0.01 at.%, p-type electrical conduction behavior was observed.
