High resolution X-ray diffractometry has been applied to study domain
misorientation in SiC epi-layers grown by the sublimation epitaxy meth
od. A pronounced effect of the growth conditions on the mosaicity of t
he epi-layer has been observed. The results are discussed in terms of
domain evolution and structural changes during the epi-growth under di
fferent growth conditions. (C) 1998 Elsevier Science B.V. All rights r
