Figure 7
(a) ZNR and ANR with 20 atoms wide. The system is periodic in x direction for ZNR and in y direction for ANR. The green and red rectangles represent the atoms in the unit cell for ZNR and ANR, respectively. Vacua of 15 Å are inserted on both sides of the nanoribbon. (b) and (c) are the optimized structure of ZNR for Nitrogen and Bismuth, respectively. (d), (e) and (f) are the optimized structure of ANR Nitrogen, Phosphorus and Bismuth, respectively.
