The valence band structure of wurtzite type materials is investigated using a k · p approximation. The E ( k ) dependence for the bands A, B, and C is completely determined by six parameters: two for k ∥ c , three for k ⟂ c and one additional parameter for a general direction. Relationships between the effective masses at k = 0 are given for the three bands. Even near k = 0 the sub‐bands are strongly non‐parabolic. The constant‐energy surfaces retain their rotational symmetry. Numerically calculated E ( k ) curves are presented for k ∥ c and k ⟂ c for CdS and CdSe.
