Figure 1From: Valence band offset of wurtzite InN/SrTiO3 heterojunction measured by x-ray photoelectron spectroscopy Spectra of InN/STO sample. 3d core level peaks for the InN and thin InN/SrTiO3 heterojunction samples, Ti 2p core level peaks for the SrTiO3 and InN/SrTiO3 heterojunction samples, and valence band photoemission for the InN and SrTiO3 samples. All peaks have been fitted using a Shirley background and Voigt (mixed Lorentzian-Gaussian) line shapes.Back to article page
