The hole mobility in Cu2O was measured using guard ring and Hall current techniques over a temperature range of +200 to −125 °C. For samples with highest mobility the temperature dependence was found to be approximately exponential with different activation energy above and below +60 °C. The results are explained on the basis of the known vibrational spectrum of Cu2O with polar scattering by an optical phonon of 0.0795 eV and nonpolar scattering by optical phonons of 0.139, 0.023, and 0.0185 eV predominating. Variations in mobility due to changes in dielectric constant are also discussed.
