Proposed mechanism of band bending for the present bilayer-TMDC heterojunctions.

(a) Calculated local density of state for the 2L WS2 and WS2/MoS2 heterojunction. (b) Schematic illustration of strain and piezoelectric polarization-induced band bending around the heterointerface. (c) Schematic illustration of the cylindrical space charge at the heterointerface and fitting results of spatial changes in ECBM from the heterointerface in the 2L WS2 region.
