Approximate calculation of electronic band structures. IV. Density of states for transition metals

摘要: Density-of-states curves for chromium, iron, nickel and copper are calculated using the band-structure scheme of Hubbard Dalton Gilat- Raubenheimer (1966) method. In each case estimates given Fermi energy density states at energy. The accuracy Gilat-Raubenheimer method is investigated by calculating density-of-states iron varying numbers k-points in Brillouin zone. It concluded that main features function accurately determined with use only 200-300 1/48 section
