Figure 8From: Ab initio calculation of valley splitting in monolayer δ-doped phosphorus in siliconBand structure and physical structure of FCC and SC cells. (a) Typical band structure of bulk Si for two-atom FCC (solid lines) and eight-atom SC cells (dotted lines with squares), calculated using the vasp plane-wave method (see ‘Methods’ section). (b) Two-atom FCC cell. (c) Eight-atom SC cell.Back to article page
