Band Structure and Fermi Surface of Antimony: Pseudopotential Approach

The band structure and Fermi surface of semimetallic Sb are determined by means of a pseudopotential approach. The pseudopotential is determined by adding to the pseudopotential of grey Sn, extrapolated from those of Si and Ge, one half of the contribution of the antisymmetric pseudopotential of InSb. The band structure shows three electron pockets located at the point $L$ of the Brillouin zone and six hole pockets with mirror symmetry. This corresponds to an assignment opposite to the conventional designation of electrons and holes. The parameters of the Fermi surface are calculated. Comparison with experiment gives very good agreement throughout.
