a, b are integrated PL intensity at MoSe2 A exciton resonance as a function of the excitation photon energy for monolayer MoSe2 (black) and MoSe2/WS2 heterojunction (red) regions at the gate voltage of −2 V (a) and the gate voltage of 4 V (b), respectively. c, d are PL enhanced factor for the gate voltage of −2 V (c) and 4 V (d), respectively.
