Tentative Structure of Molybdenum Oxycarbide

Abstract

Abstract Scanning electron microscopy (SEM), transmission electron microscopy (TEM), x-ray diffraction (XRD), and selected area electron diffraction (SAED) are employed to deduce the atomic arrangement of defect molybdenum oxycarbide. The structure is built up of fcc cells of lattice constant 0.41 nm, with semi-ordered metal vacancies giving rise to a larger, 3-fold periodicity of 1.23 nm.
