  • Monoclinic transition metal dichalcogenides offer the possibility of topological quantum devices, but they are difficult to realize. One route may be through switching from the common hexagonal phase, for which a method is now shown.

  • Electron-boson coupling is crucial for understanding many-body systems, yet the role of electron-plasmon interactions remains underexplored. Here, the authors reveal plasmonic polarons in self-intercalated 1T-TiS₂ using angle-resolved photoemission spectroscopy and high-resolution electron energy loss spectroscopy, demonstrating tunable bosonic energy scales and highlighting the potential of layered materials for advancing quantum material research.

  • Charge carrier modulation in graphene by proximate ferroelectricity has attracted much attention, but it was rarely successful especially for oxide ferroelectrics mainly due to uncontrolled interfacial charge traps. In this work, the device operation of field–effect transistor comprising of graphene and ferroelectric single-crystal Pb(Mg1/3Nb2/3)O3–PbTiO3 was carefully analyzed for studying the direct or indirect coupling phenomena between charge carriers in graphene and nearby ferroelectricity.
