Abstract
The conductivity and the Hall and Seebeck coefficients of reduced and doped strontium titanate were measured over the temperature range 4.2-300°K. An average effective mass of about 10 was deduced from these experiments. This value agrees well with the results of a recent energy-band calculation for SrTi based on a tight-binding approximation. Phonon-drag contributions to the Seebeck coefficient appear to be negligible above 50°K. Such a result is expected in view of the very small heat conductivity reported by Sievers.
