Abstract

We have examined the structural properties of InP/In_0.53Ga_0.47As 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 reveals that solid state diffusion in subsurface layers can be induced by surface stresses associated with surface roughening.
