Sy. Shiryaev et al., LOW-DIMENSIONAL STRUCTURES GENERATED BY MISFIT DISLOCATIONS IN THE BULK OF SI1-XGEX SI HETEROEPITAXIAL SYSTEMS/, Applied physics letters, 71(14), 1997, pp. 1972-1974
The capability of misfit dislocations to generate nanostructures in th
e bulk of Si1-xGex/Si heteroepitaxial systems is demonstrated. It is s
hown that dislocation slip originating from compositionally graded Si1
-xGex layers can produce a range of low-dimensional structures includi
ng nanowires, nanodots, and mosaic superlattices. Formation of the nan
ostructures is achieved in parallel processing, through a simple two-s
tep cycle which includes growth of layered planar structures and postg
rowth annealing. (C) 1997 American Institute of Physics.
