Electronic Structure of Single-Wall Silicon Nanotubes and Silicon Nanoribbons: Helical Symmetry Treatment and Effect of Dimensionality
Figure 4
Band structure of ((a), (b)) [(3,0),91], Å and ((c), (d)) [(5,0),91], Å SWSiNTs. Comparison of band structures calculated by ((a), (c)) zone-folding method and ((b), (d)) calculated directly by helical method of tube formation which account for effect of tube curvature; for details see the text.
