Anomalous electrical transport properties of disordered Ti85Al15-xFex alloys at low temperature

A systematic investigation on electron dephasing scattering rate in Ti85Al15-xFex at low temperature has been reported. The dephasing scattering rate is dominating by electron-phonon scattering and follows the saturation behaviour for the temperature T→0K. The electron-phonon scattering shows quadra...

Description
Summary:A systematic investigation on electron dephasing scattering rate in Ti85Al15-xFex at low temperature has been reported. The dephasing scattering rate is dominating by electron-phonon scattering and follows the saturation behaviour for the temperature T→0K. The electron-phonon scattering shows quadratic temperature dependence, which do not wholly agree with the theory. The nature of zero temperature dephasing scattering rates cannot be explained by the existing mechanisms and it depends strongly on disorder.
