Figure 8. (A) Variation of bandgap of GaSe/MoSi2N4 vdWHs with electric field. The illustration is a diagram of applying an electric field along the vdWHs z-direction; (B) Projected band structure of GaSe/MoSi2N4 vdWHs under different electric field intensities. vdWHs: van der Waals heterostructures; GaSe: Gallium selenide.
