Abstract
The roughness of Si(001) amorphous/crystalline interfaces, regrown by either solid phase epitaxy (SPE) or ion-beam-induced epitaxial crystal lization (IBIEC), has been studied by measuring the scattered x-ray in tensity along crystal truncation rods close to Si bulk Bragg peaks. Fo r both regrowth methods, the interface region is well described by a d iscrete roughness profile. The root-mean-square roughnesses are compar able and rather small: 8.0+/-0.6 angstrom and 7.4+/-0.6 angstrom for t he SPE and the IBIEC regrown sample, respectively. This indicates the presence of a common smoothing mechanism.
