Article summary:

1. 2D van der Waals (vdWs) heterostructures have outstanding properties, including high optical absorption, negative differential conductance, and broad-band spectrum range.

2. Type-II band alignment in 2D vdWs heterostructure offers many fascinating benefits, such as rapid carrier separation at the heterostructure interface, larger optical absorption spectral band for broadband detection, and interlayer transition mechanism that can break the bandgap limitation and achieve high optical parameters.

3. Strong binding energy is required to achieve strong interlayer transition in type-II vdWs heterostructures, which can be calculated from density functional theory. Vertical stacking technique can construct type-II band structures in vdWs heterostructures with sharp peaks in the density of states (DOS).
