There are different polarization fields on the Zn face and O face along the c-axis of the ZnO single crystal due to the influence of the spontaneous polarization. In this work we will determine the internal field directions of both faces of the 0.5mm thick ZnO single crystal by photoreflectance and contactless electroreflectance techniques. We found that Zn face has inversion phase line shape, which means its internal field directs outward; O face has same phase line shape, which means its internal field directs inward.
