Structural evolution in strained In0.18Ga0.82As stacking multilayers on vicinal GaAs surfaces

Show affiliationsStrain relaxation mechanisms for the growth of m-layers of In0.18Ga0.82As/GaAs on a GaAs(100) substrate, tilted 2° towards the [0–11] direction, have been studied by molecular beam epitaxy (MBE) and atomic force microscopy (AFM). While dislocations alone provide a strain relaxation mechanism for nominal GaAs(100), additional strain relaxation mechanisms were observed for a vicinal GaAs(100) substrate. For m ≤ 8, step bunching provided a mechanism for strain relaxation. For m ≥10, in addition to the step bunching, bunched corners along two [051] and [0–1–5] directions provided the mechanism for strain relaxation. These surface patterns provide potential to act as a template for the growth of more uniform and organized nanostructures. For m = 16, the formation of dislocations provided an additional route for strain relaxation.
