Abstract: We propose an interface model for Ge and its surface passivating nitride. The Β-Ge3N4 (0001)/Ge (111) interface structure does not have dangling bonds and is predicted to be exceptionally stable compared with other possible structures. Band offsets determined using x-ray photoemission spectroscopy study are in agreement with the prediction by first-principles calculations. The band offsets are large enough to minimize possible carrier tunneling. © 2008 American Institute of Physics.
