Fabrication and Characterization of Al/NiO Energetic Nanomultilayers

Figure 3

XPS spectra of Al/NiO nanomultilayers with modulation period thickness of 250 nm: (a) the up, middle, and down spectra show Al 2p, Ni 2p, and O 1s peaks of as-deposited nanomultilayers, respectively; (b) the up, middle, and down spectra show Al 2p, Ni 2p, and O 1s peaks of annealed nanomultilayers at 450°C, respectively.
