Hybrid surface roughening modes during low-temperature heteroepitaxy: Growth of fully-strained metastable Ge12xSnx alloys on Ge„001...231
Fully-strained single-crystal metastable Ge12xSnx alloys were grown on Ge~001! up to their critical epitaxial thickness values tepi(x) in order to probe surface roughening pathways leading to heteroepitaxial breakdown during low-temperature molecular-beam epitaxy under large compressive strain. All films with x.0.09 have comparable roughnesses while films with x,0.09 are considerably rougher wi...
متن کاملUniversality Class of Discrete Solid-on-Solid Limited Mobility Nonequilibrium Growth Models for Kinetic Surface Roughening
We investigate, using the noise reduction technique, the asymptotic universality class of the well-studied nonequilibrium limited mobility atomistic solid-on-solid surface growth models introduced byWolf and Villain (WV) and Das Sarma and Tamborenea (DT) in the context of kinetic surface roughening in ideal molecular beam epitaxy. We find essentially all the earlier conclusions regarding the un...
متن کاملRoughening transition and solid-state diffusion in short-period InPÕIn0.53Ga0.47As superlattices
We have examined the structural properties of InP/In0.53Ga0.47As superlattices grown by metalorganic molecular beam epitaxy by varying the periodicity and the total thickness. We observed a roughening transition, which involves the formation of wavy interfaces, when the period and total thickness of the superlattice exceeded critical values. Interface roughening in the wake of the growth front ...
