Crystal polaron conductivity is studied taking into account the crystal lattice deformation by a conduction electron.
In addition, the concept of phonon damping is developed which allows one to take into account fluctuation and
dissipative mechanisms of conduction electron and phonon field interaction as well as the change of the crystal lattice
dispersion law. The stochastic equation has been derived for the electron coordinate operator describing Brownian
motion of an electron in the crystal. The conductivity tensor of the system studied has been determined. |
