In 3d5/2 Core level XPS spectra for a InN and e InN/diamond samples, and C1s XPS spectra for c diamond and f InN/diamond samples. b InN and d diamond are the valence band spectra. All peaks have been fitted using a Shirley background and Voigt (mixed Lorentzian-Gaussian) line shapes, as summarized in Table 1.
