Abstract

We present an attempt to clarify the valence band order of ZnO and Mg _xZn_1-xO films grown by pulsed laser deposition (PLD) on sapphire substrates. We derive the dependence of spin orbit interaction (Δ_so) and crystal field interaction (Δ_cf) on the temperature, strain and cation replacement (Zn with Mg) and compared this with theoretical predictions. The strain was varied by using different orientated sapphire substrates (c-, r-, and m-plane orientations) and by varying the film thicknesses. All these investigations support the conclusion that the symmetry order of the valence band is Γ₇-Γ₉- Γ₇ for ZnO and Mg_xZn_1-xO for × ≤ 0.55.
