摘要：

An energy balance theory for predicting the critical thickness of the Si1-xGex/Si heterostructure is derived based on an experimentally identified dislocation generation mechanism. The theory is in close agreement with experimental results. The critical thickness predicted by this theory is about four times that by the mechanical balance theory of Matthews and Blakeslee. © 1990 IOP Publishing Ltd.
