Fig. 5: Simulations of the monolayer of Nb2n+1SinTe4n+2 (n = 1–3).
From: A tunable and unidirectional one-dimensional electronic system Nb2n+1SinTe4n+2
a–c Calculated band structures of the monolayer samples with n = 1, 2, 3 respectively. Inset of panel a is the first Brillouin zone with high symmetry points marked. d–f The real space plots of the charge densities at the α points in n = 1, 2, 3 respectively. We know the bands at Fermi levels on samples come from the c chains in real spaces. (see more charge distribution plots in Supplementary Figs. 5–7).
