Exploring high pressure structural transformations, electronic properties and superconducting properties of MH2 (M = Nb, Ta)

Exploring high pressure structural transformations, electronic properties and superconducting properties of MH2 (M = Nb, Ta)

The high-pressure structures and properties of MH2 (M = Nb, Ta) are explored through an ab initio evolutionary algorithm for crystal structure prediction and first-principles calculations. It is found that NbH2 undergoes a phase transition from a cubic Fm3¯m structure with regular NbH8 cubes to an o...
