Deformation potentials and internal strain parameter of silicon.

Christensen N.E.

The deformation potentials for the splitting of the Lambda 25' state at the top of the valence band of Si under trigonal strain have been calculated as a function of the internal strain parameters zeta . The calculations, relativistic LMTO, were made with and without inclusion of spin-orbit coupling. The deformation potentials that agree with experiments correspond to 0.4
