"Unveiling the atomic and electronic structure of the VN/MgO interface";
Physical Review B,
We report a quantitative comparison of the interface structure of VN/MgO 001 using ab initio densityfunctional
theory DFT , aberration-corrected high-resolution transmission electron microscopy HRTEM , and
electron energy-loss spectroscopy EELS . By HRTEM, we show an atomic resolution structure of epitaxially
grown VN film on MgO with a clearly resolved oxygen and nitrogen sublattice across the interface. As
revealed by DFT, the 002 interplanar spacing oscillates in the first several VN layers across the interface.
Interfacial chemistry determined by EELS analysis shows the preponderance of O and V atom at the interface,
resulting in a small detectable core-level shift.
