摘要：
The microstructure of InxGa1-xAs/GaAs (5nm/5 nm, x=0 to 1.0), as grown by a metalorganic chemical vapor deposition two-step growth technique on Si(100) at 450 degree C, and subsequently annealed at 750 degree C, is investigated using plan-view and cross-sectional transmission electron microscopy. The variations in resultant island morphology and strain as a function of the In content were examined through the comparison of the misfit dislocation arrays and moires observed. The results are discussed in relation to the ways in which the island relaxation process changes for high In content.
