Figure 3: XPS characterizations of h-BN-coated Ni foils.
From: Ultrathin high-temperature oxidation-resistant coatings of hexagonal boron nitride
(a) Schematic shows the etching process of h-BN-coated Ni foil. (b–d) The XPS spectra of Ni (2p3), N (1 s) and B (1 s), respectively, acquired after each etching. The arrows indicate the evolution of the spectra. (e–f) Relative atomic concentration and intensity of each element versus sputtering time. (g–i) Individual Ni XPS spectra of pure Ni, 2 nm h-BN-coated Ni and 5 nm h-BN-coated Ni foils after oxidation testing.
