Electron–Electron Scattering and Resistivity in Non-Centrosymmetric Metals

The quadratic low-temperature dependence of resistance in ordinary metals is determined by the momentum relaxation due to electron-electron scattering presence Umklapp processes and on impurities. In without inversion center spin-orbit interaction electrons with crystal lattice lifts spin degeneracy electron states splits each band two bands. temperature collisions rate found using matrix kinetic equation including electron-impurity intra inter scattering. It shown that clean enough case when energy splitting exceeds but at same time it much smaller than Fermi square resistivity still valid.
