Abstract

The temperature and thermoelastic fields in growth systems are considered theoretically in order to assess their effect on the optical symmetry of the growing crystal. The process is modeled using three-dimensional curvilinear coordinates to describe a closed, low-strain thermoelastic system, with allowance made for the temperature variations of the thermal properties of the multilayer growth system and nonlinear and unsteady-state processes with arbitrary boundary conditions. The results, presented as plots of the strain, stress, displacement, and temperature fields, demonstrate the potential of the method for designing new growth units and improving the existing ones and suggest that crystals without frustration of optical symmetry can, in principle, be grown.
