Atomic-level investigation of surface processes governing SiGe wetting layer formation using STM/STS
… energy of 0.7 ± 0.2 eV and an associated prefactor of 5 x 104±2 s—1 are computed. Both of these kinetic values are quite low as compared to typical surface diffusion phenomena, and we suggest that the transition mechanism is likely complex and multi-bodied, requiring concerted …
