Pressure-induced structural phase transformation and elastic properties of transition metal mononitrides
TL;DR: In this paper, the high pressure structural phase transition in six transition metal mononitrides (TMNs) (M=Ti, Mo, V, Nb, Hf, and Zr), have been studied using a two-body interionic potential theory which includes the effect of Coulomb screening due to the semi-metallic nature of these compounds.
