Extensions of the tetrahedron method for evaluating spectral properties of solids
Abstract
Two extensions of the widely used tetrahedron method for the evaluation of spectral properties of solids are presented. The first provides explicit formulae for including matrix element variation inside tetrahedral microzones in the same spirit in which the energy variation is included in the original method. The second is a scheme for using local quadratic interpolation inside some tetrahedra to provide the matrix element and energy values required to apply the tetrahedron method to a large number of tetrahedra into which the original tetrahedra have been divided. This scheme is similar to the hybrid method of extension of the Gilat-Raubenheimer method. Application to the calculation of the density of states of a single tight-binding band in a FCC crystal shows that its efficiency is comparable with that of the method recently proposed by Chen (1977).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
