Abstract

The thermoelastic stress distribution in growing 6H SiC crystals was simulated using a two dimensional finite element model. Based on the calculated stress distribution, possible plastic deformation of the material was postulated. High resolution x-ray diffraction (HRXRD) was used to detect the net deformation and residual stresses in the grown crystals. The results were in agreement with the postulated plastic deformation.
