Tunable SnO₂ Nanoribbon by Electric Fields and Hydrogen Passivation

Figure 1

The structure model of (4 × 1 × 1) zigzag and (1 × 4 × 1) armchair SnO₂ nanoribbon for different hydrogen passivation (a–f) and the transport model (h) ( is the growth direction of nanoribbons and is the direction of external electronic field). The big gray balls are Sn atoms, the small red balls are O atoms and the pink balls are H atom. In addition, the red-dotted lines would represent the unit cell.
