Electronic Structure of Single-Wall Silicon Nanotubes and Silicon Nanoribbons: Helical Symmetry Treatment and Effect of Dimensionality
Figure 6
Effect of electron-vibration coupling on band structure topology at Fermi level for -type SWSiNT. Band structure at (a) equilibrium undergoes topology change at Fermi level for (b) displacement of 0.039 Å/Si-atom out of equilibrium at vibration motion in stretching Si–Si mode; cf. path 0- for (a)/(b) panels.
