- Abstract
We report the high-pressure synthesis and elastic properties of stoichiometric cubic δ-NbN investigated by a combination of experiments and first principles calculations. Using the high pressure solid-state ion-exchange reaction route, we have successfully synthesized polycrystalline δ-NbN at 5.5 GPa and 1673 K. The refined lattice parameter of as-synthesized sample is 4.3960(6) Å, corresponding to the stoichiometric niobium nitride. The determined bulk modulus of δ-NbN is B0 = 319(2) GPa with
