To facilitate the implementation of accurate Brillouin zone integration codes fordiamond-type semiconductors such as Si we have constructed a new “irreduciblewedge” to be used in conjunction with tetrahedral k-space interpolations. This newwedge, defined by the vertices (000), (100), (110) and (121212) (normalized to |X| = 1),spans portions of the first three Brillouin zones and contains the equivalent of 1/48 of aBrillouin zone volume. Simple symmetry arguments may be used to establish theequivalency of this new wedge with the standard irreducible wedge
