Si1-xGex critical thickness for surface wave generation during UHV-CVD growth at 525\ub0C
No full textSeveral Si1-xGex/Si heterostructures were grown at 525\ub0C using a commercially available UHV-CVD reactor. Layers with a germanium fraction ranging from 0.15 to 0.5 were examined by means of cross-sectional transmission electron microscopy and atomic force microscopy. Surface waves were found in layers with a thickness above a critical value which decreases rapidly as the Ge fraction is increased. Both experimental and modeling results show that surface waves are generated before misfit dislocations for Ge fractions above 0.3.Peer reviewed: YesNRC publication: Ye
