Three dimensional Kinetic Monte Carlo simulations on super-lattices were applied to study the evolution of several types of stacking faults during homo-epitaxial growths of (11•0) misoriented 4H silicon carbide. It was shown that these defects can either propagate throughout the entire epilayer (i.e. extended from the substrate up to the surface) or close in dislocation loops, in dependence on the surface kinetics. Furthermore, it was demonstrated that the surface instability rules both stacking fault propagation and step bunching mechanism.
