Relations are derived for the Sublattice displacements in zincblende‐type crystals if the deformation is caused purely mechanically or electrically. The ratio of the two internal displacements induced by field ( d α E ) and strain ( d α T ) is expressed in terms of characteristic crystal constants. A plot of d α E/d α Tversus the internal strain parameter ζ for the various zincblende‐type materials shows a strong increase of the Sublattice displacement ratio for ζ → 1 and a change of sign at ζ = 1.
