چکیده

The effect of #110$ uniaxial stresses up to 1.5 GPa on defect nucleation during solid phase epitaxy of amorphous !001" Si created via ion implantation was examined. The solid phase epitaxial regrowth velocity was slowed in compression. However, in tension, the velocity was unaffected. Both compression and tension resulted in an increase in regrowth defects compared to the stress-free case. The defects in compression appear to arise from roughening of the crystallizing interface whereas in tension it is proposed that reorientation of crystallites near the initial amorphous/ crystalline interface is responsible for defect formation. © 2007 American Institute of Physics. #DOI: 10.1063/1.2801518$

Stressed solid-phase epitaxial growth of (011) Si

The solid-phase epitaxial growth kinetics of amorphized (011) Si with application of in-plane 2 11 1⁄2 uniaxial stress to magnitude of 0.9 0.1 GPa were studied. Tensile stresses did not appreciably change the growth velocity compared with the stress-free case, whereas compression tended to retard the growth velocity to approximately one-half the stress-free value. The results are explained usin...

Morphological evolution of cobalt germanide epilayers, CoxGey, was investigated in situ by scanning tunneling microscopy and spectroscopy and reflection high-energy electron diffraction, as a function of deposition method and, hence, the phase content of the epilayer. During reactive deposition epitaxy, in which Co atoms were evaporated onto a flat pseudomorphic Ge/Si(001) wetting layer at 773 ...

Kinetics and morphological instabilities of stressed solid-solid phase transformations.

An atomistic model of the growth kinetics of stressed solid-solid phase transformations is presented. Solid phase epitaxial growth of (001) Si was used for comparison of new and prior models with experiments. The results indicate that the migration of crystal island ledges in the growth interface may involve coordinated atomic motion. The model accounts for morphological instabilities during st...

On Kinetically vs. Energetically Driven Growth Instabilities in Solid and Vapor Phase Epitaxy

A stress-induced kinetically-driven morphological instability is of general applicability to driven systems. The effect of stress on the reaction mobility for incorporation into the growing solid couples to stress variations along a perturbed planar growth front, resulting in amplification or decay of the perturbation depending on the sign of the stress. Experimentally we studied a model system...
