Investigation of the phase formation wave in the model of solid state amorphization

Computation results of the model of solid state amorphization (SSA) based o n a general approach to non-equilibrium phase transitions are reported. The model takes into account the mutual interaction of the structural elements of the amorphous phase via a deformation field. For the experimental param eters, corresponding to semiconductors undergoing amorphization by high-pre ssure treatment, a family of self-sustaining autowave solutions in the form of a traveling front, a traveling pulse and a series of pulses associated with the traveling front was obtained. The relation of these solutions with the expected morphology of amorphous samples produced by SSA is discussed. (C) 2000 Elsevier Science B.V. All rights reserved.
