Research paperExperimental CharacterizationTheoreticalElectron-phonon coupling across the TMD/hBN van der Waals interfaceG. Gatti, C. Berthod, J. Issing, M. Straub et al.arXiv preprint·2026·10.1021/acsnano.4c07805·arXiv:2604.24139AbstractMany-body interactions can couple electronic states in one layer with collective excitations in the adjacent layer, providing a route to tailor properties of heterostructures. Here, the authors use micro-focus ARPES to map monolayer WS₂ and WSe₂ on hBN, with and without an intermediate graphite layer, and identify replica bands that indicate long-range interfacial electron-phonon coupling. A modified Fröhlich model provides semi-quantitative agreement with the observed spectral functions.Read more
