Fig. 5: Calculated electronic band structures.
From: Record high Tc element superconductivity achieved in titanium
a Ti-ω at 20 GPa, b Ti-γ at 100 GPa, and c Ti-δ at 180 GPa. The contributions from the s electron and d electron states are shown by red and gray circles, respectively, and the circle areas are proportional to the weights of the corresponding band states. Energy is measured relative to the Fermi energy E.
