The resistivity, the Hall, the magneto-resistance, and the Seebeck effects are investigated with respect to the highly purified single crystals of tellurium over the temperatures ranging from -190°to +300℃. The said crystals are found to be a P-type extrinsic semiconductor at low temperatures, while an intrinsic conduction supersedes it above ice point. The energy gap between the conduction band and the normally filled band are estimated at 0.34 eV. In terms of the electric and the galvanomagnetic data, the concentrations, the mobilities, the effective masses, and the mean free paths of positive holes and electrons are expressed as functions of temperature. The thermo-electric data are also compatible with the above results.
