20], [1210] and [2110]) of MoS2 (0001) substrate, respectively. The AFM measurements show that the growth of CuPc on MoS2 (0001) occurs in a Stranski-Krastanov mode. The CuPc molecule can be flat-laying on MoS2(0001) at low coverage (~0.3 nm), but form strip-like crystals along the surface crystal axes of MoS2 (0001) at high coverage (>2.4 nm). The CuPc molecule shows obvious anisotropy, indicating that the molecular plane is not parallel to the MoS2 surface. The PES measurements show there is no charge transfer process at the interface, indicating weak van der Waals interaction between CuPc and MoS2(0001)."/>     van der Waals heterostructure about CuPc/MoS<sub>2</sub>(0001)
