It should mention that the intensities of the Ni2P and B2p XPS peaks of the sample annealed at 300C are much stronger than those of the as-prepared and 400C annealed samples. Usually,the intensities of the XPS peaks are related to the detected photocurrent intensity, namely (i.e.,) the amounts of the collected photoelectrons, which in turn are affacted by the roughness of the surface. In our experiments, the XPS measurments for the as-prepared, 300C and 400C annealed samples were perfomed under the same experimental conditions with the same thicknesses. As shown in Fig 4(d), these three samples show almost all identical Al2p XPS peak intensities. However, the Ni2p and B2p XPS peak intensities are apparently much stronger for the samples annealed at 300C than those of the as-prepared and 400C annealed samples, which strongly suggests that the quality of the NiB/Al interface of the sample annealed at 300C is much better than that of the as-prepared and 400C annealed samples. |
