Caption

Schematic crystal structures and electronic localization functions (ELFs) of 2D, 1D, and soft 1D Bi2Se3, Sb2Se3 and BiSeI, respectively. Schematic diagrams and corresponding crystal structures of (a, d) 2D slabs in Bi2Se3, (b, e) 1D chain in Sb2Se3 and (c, f) 1D chain with migration of halogens in BiSeI. The crystal structures of Bi2Se3, Sb2Se3and BiSeI viewed along the c direction are given in (g-i), respectively. (j-l) The projected ELF along the chain. The isosurface level of ELF is 0.9.
