By spherical aberration (CS)-corrected high-resolution transmission electron microscopy (HRTEM) and electron energy-loss spectroscopy (EELS), the atomic and electronic structures at the CrN/Cr interface are studied. A transition layer is formed at the CrN/Cr interface, which is identified as hexagonal Cr(2)N. The atomic structures at the interfaces are revealed. The elemental concentration distribution across the interface was quantified by EELS. The fine structures of Cr-L(2,3) in Cr, CrN, and Cr(2)N exhibit a subtle difference. The Cr-L(2,3) edge in CrN shows a noticeable chemical shift as compared to Cr and Cr(2)N, accompanied by a slight variation at the corresponding N-K edge.
