Abstract :
Composition of the first atomic layer at the crystal-vacuum interface is calculated for coherent SiGe epilayers grown on Si and Ge substrates with (100) and orientations. Comparison with similar data for bulk unstrained alloy crystals reveals significant differences in segregation behaviour between pseudomorphic and bulk crystals
