Research paperExperimental CharacterizationUltrafast response of spontaneous photovoltaic effect in 3R-MoS₂-based heterostructuresJingda Wu, Dongyang Yang, Jing Liang, Max Werner et al.2022·10.48550/arxiv.2211.06746·arXiv:2211.06746AbstractWe investigate ultrafast photocurrent dynamics in graphene/3R-MoS₂/graphene heterostructures. Photocurrent autocorrelation reveals a fast picosecond component and a slower thermal recovery component, while non-degenerate pump-probe photocurrent spectroscopy separates thermal from electronic contributions. The devices show spontaneous photovoltaic behavior, strong temperature dependence, and an external quantum efficiency near 10% at the A-exciton resonance.Read more
