ABSTRACT
High pressure investigation of niobium oxynitrides (NbN0.98O0.02) employing synchrotron based angle dispersive x-ray diffraction experiments was carried out in very fine pressure steps using membrane driven diamond anvil cell. Ambient cubic phase was found to be stable up to ~18 GPa. At further high pressure cubic phase showed rhombohedral distortion.
