Band Structure of White Tin

Abstract

A perturbation calculation of the band structure in white tin is performed using the orthogonalized plane wave approximation. The energies are determined for several points of high symmetry of the Brillouin zone for different choices of potential. On the basis of these results the properties of the Fermi surface in the neighborhood of these points are discussed. It is found that the first two Brillouin zones are completely filled with electrons.
