Abstract:
Buried dislocation networks obtained by Si(001) wafer bonding pattern the free surface of the sample, giving rise to long-range undulations and short-range embossing, respectively, for flexion and rotation misalignement. Comparison with continuum-elasticity calculations reveals that this patterning is enhanced by strain-driven overetching. These surfaces are a template for growth, and we show that Ge quantum dots can be ordered with a fourfold symmetry by proceeding a postgrowth annealing.
