Electronic band structure along high symmetry lines of the Brillouin zone (top) and the Fermi surface (bottom) of CaC6 in the Pmmn phase at 39 GPa.
The energy bands crossing the Fermi level are labelled as 1, 2, 3 and 4, respectively. The projected Ca-d and C3- and C4-p electron characters are denoted by red circle and blue square, respectively.
