Research paperExperimental GrowthExperimental CharacterizationComputational DFTHybridization in van der Waals epitaxy of PtSe₂/h-BN and PtSe₂/graphene heterostructuresMeryem Bouaziz, Samir El Masaoudi, Aymen Mahmoudi, Eva Desgué et al.2025·10.48550/arxiv.2510.17464·arXiv:2510.17464AbstractVan der Waals heterostructures combining platinum diselenide (PtSe₂) with h-BN and graphene were studied using molecular beam epitaxy (MBE), Raman spectroscopy, nano-ARPES, and density functional theory. The work compares PtSe₂/h-BN and PtSe₂/graphene and finds stronger interlayer hybridization for PtSe₂ on graphene, evidenced by minigap openings in graphene π bands. The monolayer PtSe₂ valence band maximum is reported at different binding energies on h-BN and graphene substrates.Read more
