Abstract | 2D material-based heterostructures are constructed by stacking or spicing individual 2D layers to create an interface between them, which have exotic properties. Here, a new strategy for the in situ growth of large numbers of 2D heterostructures on the centimeter-scale substrate is developed. In the method, large numbers of 2D MoS2, MoO2, or their heterostructures of MoO2/MoS2 are controllably grown in the same setup by simply tuning the gap distance between metal precursor and growth substrate, which changes the concentration of metal precursors feed. A lateral force microscope is used first to identify the locations of each material in the heterostructures, which have MoO2 on the top of MoS2. Noteworthy, the creation of a clean interface between atomic thin MoO2 (metallic) and MoS2 (semiconducting) results in a different electronic structure compared with pure MoO2 and MoS2. Theoretical calculations show that the charge redistribution at such an interface results in an improved HER performance on the MoO2/MoS2 heterostructures, showing an overpotential of 60 mV at 10 mA cm(-2) and a Tafel slope of 47 mV dec(-1). This work reports a new strategy for the in situ growth of heterostructures on large-scale substrates and provides platforms to exploit their applications. |
