Research paperExperimental CharacterizationSpectroscopic Evidence for Interfacial Charge Separation and Recombination in Graphene-MoS₂ Vertical HeterostructuresYuqing Zou, Zeyu Zhang, Chunwei Wang, Yifan Cheng et al.2025·10.48550/arxiv.2304.08724·arXiv:2304.08724AbstractVertical van der Waals heterostructures of graphene and MoS₂ are studied by time-resolved terahertz spectroscopy, terahertz emission spectroscopy, and transient absorption spectroscopy to probe interfacial charge separation, stacking-order effects, and recombination dynamics. The results show stacking-order-dependent carrier transfer behavior under sub-A-exciton excitation and a recombination timescale ranging from 18 ps to 1 ns, influenced by defect density in MoS2.Read more
