Modulation Electronic Properties of Silicane/SnSe₂ Van der Waals Heterostructures Using External Force and Electric Field

Figure 2

Depictions of the lattice structures (2×2) of the silicane/SnSe₂ vdW heterostructure, in which (a) Model-I, (b) Model-II, (c) Model-III, (d) Model-IV, (e) Model-V, and (f) Model-VI are illustrated. The upper diagrams show the top view, while the lower ones are the side view. The unit cells are represented by the black lines.
