Fig. 2: Fermi surface and the Brillouin zone of antimony (Sb).

a The Fermi surface consists of electron pockets (in green) and hole pockets (in red). All pockets are located at zone boundaries and have a mirror counterpart due to the inversion symmetry. The Brillouin zone of the A7 crystal structure, nearly a truncated cuboctahedron, is shown by black solid lines. b Projection to the trigonal plane. c The Fermi surface of holes centered at the T-point. This structure, dubbed ZONY23, consists of six interconnected pockets (shown in orange).
