Missing dimers and strain relief in Ge films on Si(100)

View publication

Abstract

The 2×8 reconstruction of Ge films of Si(100) is shown to arise from ordered arrays of rebonded missing dimers (RMD s). Such a reconstruction was suggested by Pandey for Si(100). However, because of their large tensile stress, RMD s are much more energetically favorable in epitaxially compressed Ge films. For Si(100), RMD s have a very small energy, and their presence may account for the puzzling discrepancy between theory and experiment for the stress anisotropy. © 1992 The American Physical Society.
