Fig. 3: Electronic structures of M2B2, M2B2H, and M2B2H4 (M = V, Nb).
From: High-Tc 2D ambient BCS superconductors in hydrogenated transition-metal borides
The electronic structures of the 2D non-, mono-, and fully-hydrogenated compounds include the orbital-resolved band structure, the projected electronic density of states for the d-orbitals of the transition metals V and Nb, the p-orbitals of boron atoms, the s-orbitals of hydrogen atoms, and the Fermi surfaces.
