3.4 Band Structure of Strained SiGe layers

Within linear deformation-potential theory only shift of valleys is taken into account whereas their shape is unchanged. This shift is described by general expressions (3.30) and (3.31). These expressions are used to calculate the energy splitting and the shift of the mean energy of the

and

valleys for the three most important substrate orientations. Generalization for the case of an arbitrary substrate orientation is straightforward.
