| Abstract | Hybrid structures assembled by van der Waals (vdW) interactions greatly expand the conventional material platforms, as there is no constraint of lattice matching in the materials design. However, a general challenge lies in the controllable assembly of 1D-2D hybrids with strong-coupled interfaces, because the interaction area is very small and is easily disturbed by exotic molecules. Here, we report the direct construction of 1D carbon nanotube-2D MoS2 monolayer hybrids with strong interfacial coupling using a sequential chemical vapour deposition growth method. The strong mechanical and electronic couplings between the nanotubes and MoS2 are unambiguously illustrated from the Raman-mode frequency shift and ultrafast interfacial charge transfer (similar to 100 fs). The findings in this work will boost the mass fabrication of 1D-2D vdW hybrid materials with controllable interfacial geometry and coupling strength, and pave the way for their future applications in electronics, optoelectronics and photovoltaics. |
