X-ray photoelectron spectroscopy was used to measure the valence band offset at the ZnO/Zn0.85Mg0.15O heterojunction grown by plasma-assisted molecular beam epitaxy. The valence band offset (Delta EV) is determined to be 0.13 eV. According to the experimental band gap of 3.68 eV for the Zn0.85Mg0.15O, the conduction band offset (Delta EC) in this system was calculated to be 0.18 eV. The Delta Ec: Delta Ev in ZnO/Zn0.85Mg0.15O heterojunction was estimated to be 3:2. (C) 2008 American Institute of Physics.
