Electronic Structure of Single-Wall Silicon Nanotubes and Silicon Nanoribbons: Helical Symmetry Treatment and Effect of Dimensionality
Figure 7
Effect of electron-vibration coupling on band structure topology at Fermi level for -type SWSiNT. Band structure at (a) equilibrium remains without change of topology at Fermi level (cf. path 0- for (a)/(b) panels) for (b) vibration motion in stretching Si–Si mode, which induces topology change in [(5,0),91]-type SWSiNT; cf. Figure 6(b)/Figure 7(b).
