Abstract
Electron mobilities in reduced and doped SrTi have been deduced from measurements of the conductivity and Hall coefficient between 1 and 1000°K. Above room temperature, scattering by the highest two longitudinal optical modes determines the mobility. Expressions based on intermediate electron-phonon coupling yield good agreement with experimental results. Below 10°K experiments indicate that ionized impurity scattering is the dominant collision process. Using a screened Coulomb potential, one obtains mobility values of the right order of magnitude.
