Abstract

The multimode nonlinear theory of formation of surface periodic point defect-deformational (DD) structures is developed. The general set of coupled nonlinear kinetic equations for DD- gratings Fourier amplitudes is derived and reduced to rate equation with allowance for diffusion and drift in q-space. The conditions of generation of either multimode or single mode DD-structures are cleared out and periods, times of formation and stationary amplitudes of DD-grating are determined. The theoretical results are used for interpretation of previously obtained experimental results on DD-gratings generation in Si under millisecond laser irradiation and under ion implantation.
