We have found two modes of growth with different growth stress. Films grown in one mode have rough surfaces and low stress. The second mode leads to smooth surfaces but the films contain many cracks due to high growth stress. A combination of these modes allows growth of films without cracks and with smooth surfaces. 621.315.592 HVPE gallium nitride growth modes morphology growth stress crack surface film https://physmath.spbstu.ru/article/2011.12.2/
