It is found that the band offsets are independent of the type of interfacial bond, while the valence band offset, VBO, decreases linearly with x as VBO = 0.143 - 0.153x eV and the inferred conduction band offset CBO (the band-gap difference minus the valence band offset) decreases linearly as CBO = 0.236 - 0.590x eV for 0.0 ≤ x ≤ 0.20.||Source Title:||Journal of Physics Condensed Matter||URI:||http://scholarbank.nus.edu.sg/handle/10635/80437||ISSN:||09538984||DOI:||10.1088/0953-8984/10/3/010|
