We investigated the potential transmission effect of graphene during van der Waals epitaxy by growing monolayer MoS₂ on monolayer graphene (MG) and twisted bilayer graphene (TBG) using the CVD method. On MG, MoS₂ grew with an orientation aligned to the graphene lattice, consistent with previous studies. On TBG, MoS₂ showed two distinct orientations, each corresponding to the alignment of the two graphene layers. This result demonstrates that the potential of the lower graphene layer penetrates through the upper graphene layer and influences the growth orientation of MoS₂. Our findings provide experimental evidence that graphene’s potential is transmitted through layers in van der Waals epitaxy, affecting crystal growth.
