Figure 2

In3d spectra recorded on InN (a) and InN/BTO (e), Ti2p spectra on BTO (c) and InN/BTO (f), and VB spectra for InN (b) and BTO (d). All peaks have been fitted to Voigt line shapes using Shirley background, and the VBM values are determined by linear extrapolation of the leading edge to the base line. The errors in the peak positions and VBM are ±0.03 and ±0.06 eV, respectively.
