Tuning Electronic Properties of GaSe/Silicane Van der Waals Heterostructure by External Electric Field and Strain: A First-Principle Study

Figure 1

The lattice structure of GaSe/SiH vdW heterostructure: (a) model I, (b) model II, (c) model III, (d) model IV, (e) model V, and (f) model VI. The upper part is for top view, and the lower part is for side view. The Ga, Se, Si, and H atoms are represented by brown, yellow, golden yellow, and white balls, respectively.
