Solitary charge-density wave in an ensemble of dislocations
Maksimov I. L. , Sarafanov G. F.
The nonlinear dynamics of perturbations of the dislocation density and of the dislocation charge density is analyzed on the basis of a system of evolution equations. A solitary wave exists in an ensemble of dislocations. It takes the form of a jump for the total dislocation density and the form of a soliton for the excess density. The stability of the self-similar solutions found is analyzed. There is a region of parameter values in which steady-state wave solutions are stable. The spectrum of possible values of the propagation velocity of a solitary wave is found. © 1995 American Institute of Physics.
