Can NbO Keep nbo Topology under Electrons? –Unveiling Novel Aspects of Niobium Monoxide at the Atomic Scale

open access: yesChemistry – A European Journal, 2023
AbstractA precise investigation of NbO has been carried out by advanced electron microscopy combined with powder and single crystal X‐ray diffraction (XRD). The structure of pristine NbO has been determined as Pm‐3 m space group (SG) with a = 4.211 Å and the positions of Nb and O at the 3c and 3d Wyckoff positions, respectively, which is consistent ...
