Abstract
We reveal the presence of atomic short-range ordering at the interface between crystalline and amorphous using aberration-corrected scanning transmission electron microscopy. We show that the first atomic layers of the amorphous film reconstruct taking on the crystalline form of . Furthermore, we find that there is a nonuniform interatomic mixing of oxygen and nitrogen at different atomic sites at the interface. The work provides a direct look at the atomic structure of crystal/amorphous interfaces composed of light elements.
