Spectroscopic investigations of band offsets of MgO|Al x Ga 1-x N epitaxial heterostructures with varying AlN content.

Epitaxial (111) Mg0 films were prepared on (0001) Al x Ga 1-x N via molecular-beam epitaxy for x=0 to x=0.67. Valence band offsets of Mg0 to Al x Ga 1-x N were measured using X-ray photoelectron spectroscopy as 1.65 ± 0.07 eV, 1.36 ± 0.05 eV, and1.05 ± 0.09 eV for x=0, 0.28, and 0.67, respectively. This yielded conduction band offsets of 2.75 eV, 2.39 eV, and 1.63 eV for x=0, 0.28, and 0.67, respectively. All band offsets measured between Mg0 and Al x Ga 1-x N provide a > 1 eV barrier height to the semiconductor.
