WebUp: Next: 3.7 The kp method 3.6.3 Strain-Induced Valence Band Splitting The deformation potential theory for the valence bands is different from that for the conduction bands because of the degeneracy of the valence bands at the valence band maximum. The operators are no longer scalars. Instead, they can be expressed as matrices.
