“…The slope of the fitting line was positive, indicating that the Ni60, Ni60–Al, and Ni60–Al–Ti coatings were n‐type semiconductors. [ 41 ] Moreover, N D was used to evaluate the conductivity of passive film, [ 42 ] in which the low N D meant the high resistance of the passive film. It was indicated that the passive film had a stronger protective effect on the coating.…”

“…Using the Eq. 5 (N V = 5.57×10 18 cm −3 ), 31,32,47 the valence band edge positions are calculated as 0.34 and 0.45 V vs Ag/AgCl for and C-550 samples in the dark condition, respectively. Considering that E VB of p-type conductivity of CuO curved nanowires (C-50) is more approximate to the E fb of CuO, it indicated a higher doping level in the CuO curved nanowires comparing to the CuO vertical nanowires (C-550).…”

“…The p-and n-type characters of NiO and TiO 2 were probed using Mott-Schottky plots (Figure S5). Typical negative and positive slopes for NiO and TiO 2 , respectively, con rmed their p-and n-type nature [50,51]. A charge carrier separation scheme based on scavenging experiments and the inherent p-and n-type natures of NiO and TiO 2 , respectively, is proposed in Fig.…”
