(color online) Electrochemical (Mott-Schottky) and photoelectrochemical characterization of ZnO:N prepared at 250 °C (blue ellipse), 550 °C (red ellipse), and ZnO-ref (gray ellipse). The comparison with the ternary phase diagram reporting the compositions of all compounds suggests that ZnO poor nitrogen-doped samples are of p-type while Zn-rich samples are of n-type (on = under illumination, off = in the dark).[106]
