Soliton Perturbations of the Charged Dislocation Core in a Semiconductor Crystal

Abstract

We consider the wave processes in a hole gas inside an electric field created by the charge distribution of donors and acceptors near a negatively charged dislocation in a semiconductor crystal of n-type. It is shown that the solution of the Korteweg–de Vries equation describes solitary waves propagating along the axis of the Read’s cylinder. The soliton velocity is estimated for the values of physical parameters characterizing the semiconductor crystal and the region near the dislocation.
