Nonequilibrium kinetics of the electronphonon sybsystem of a crystal in a strong electric field as a base of the electroplastic effect
Abstract
We present the results of a kinetic analysis of nonequilibrium dynamics of the electronphonon system of a crystal in a strong electric field based on the proposed method of numerically solving a set of Boltzmann equations for electron and phonon distribution functions without expanding the electron distribution function into a series in the phonon energy. It is shown that the electric field action excites the electron subsystem, which by transferring energy to the phonon subsystem creates a large amount of shortwave phonons that effectively influence the lattice defects (point, lines, boundaries of different phases), which results in a redistribution of and decrease in the lattice defect density, in damage healing, in a decrease in the local peak stress, and a decrease in the degradation level of the construction material properties.
