(Color online) data of the samples with different pretreatments.
(Color online) data of the untreated (circle), the treated (triangle), and the boiling treated samples. The inset illustrates the definition of the parameter and the parameter. The solid lines are the fitted curves.
(Color online) S(E) plot of the data obtained from the , the , and the boiling treated samples.
Intensities of XPS signals (in atomic ratio) found in the nontreated and the treated -type ZnO samples.
Fitted results of the data shown in Fig. 2. The indices , 1, 2, and in the parameter and the diffusion length denote the surface, the first layer, the second layer and the bulk, respectively, while and are the boundary positions of the first and the second layers, respectively.
