ABSTRACTThe energy differences between various SiC polytypes are calculated using the full-potential linear muffin-tin orbital method and analyzed in terms of the anisotropie next nearest neighbor interaction (ANNNI) model. The fact that J1 + 2J2 < 0 with J1 > 0 implies that twin boundaries in otherwise cubic material are favorable unless twins occur as nearest neighbor layers. Contrary to some other recent calculations we find J1 > |J2|. We discuss the consequences of this for stabilization of cubic SiC in epitaxial growth, including considerations of the island size effects.

Abstract On the basis of expressions obtained earlier, numerical calculations of relative donor quantum yields in the presence of multi-stage dipole-dipole energy transfer and material diffusion are carried out. Transfer rates of the second order obtained from the numerical solution of the diffusion equation with reflecting boundary conditions are used in the calculations. The results reflect the influence of donor and acceptor concentration, magnitude of diffusion coefficients and molecular size effects.
