Highlights
The bandgap in 2D van der Waals heterostructures (vdWHs) can be tuned by choosing different layers.
Change in the lateral dimension and/or stress can tune the bandgap of vdWHs.
The p-n junctions can be created by 2D layers in vdWHs.
Low-power LEDs can be made by using single-photon emitting sites in 2D layers of vdWHs.
Visible to near-infrared emission can be obtained by bandgap tuning in vdWHs LEDs.
