Three-dimensional BP colloidal crystals. (A) Energetically favorable FCC colloidal crystal in BP I, (B) stable colloidal crystals in BP I with simple cubic (SC) and BCC unit cell, (C) the most energetically favorable BCC colloidal crystal in BP II, and (D) stable colloidal crystals in BP II with SC and four particle configuration (4PC) unit cell. In BP I, disclination lines are drawn as isosurfaces of degree of order S = 0.23 (Sbulk = 0.40), particle radius is r = 70 nm. In BP II, disclination lines are visualized as isosurfaces of S = 0.1 (Sbulk = 0.26), r = 50 nm. In all cases 2 × 2 × 2 unit cells have been shown to better illustrate the structure.
