Abstract:
The main goal of present thesis is investigation of the effect of dissipative processes on the dynamics of dislocations and kinks. There were solved the following problems: a. Calculation of velocity dependence of dislocation electronic damping to revise the efficiency of electron interaction with short-wave dislocation phonons. b. Determining the velocity- and field dependence of dislocation electronic damping in an applied magnetic field. c. Calculation of kink depending probability from the point obstacle at various values of the medium viscosity coefficient to determine in each case the particular depinning mechanism.
