However, ferroelectricity, the presence of a spontaneous electric polarization, which is important in many practical applications, has rarely been reported in such materials so far. Here we employ first-principles calculations to discover a branch of the 2D materials family, based on In 2 Se 3 and other III 2 -VI 3 van der Waals materials, that exhibits room-temperature ferroelectricity with reversible spontaneous electric polarization in both out-of-plane and in-plane orientations. The device potential of these 2D ferroelectric materials is further demonstrated using the examples of van der Waals heterostructures of In 2 Se 3 /graphene, exhibiting a tunable Schottky barrier, and In 2 Se 3 /WSe 2 , showing a significant band gap reduction in the combined system. These findings promise to substantially broaden the tunability of van der Waals heterostructures for a wide range of applications.","abstract_license":"CC-BY (publisher license, via OpenAlex)","license":"cc-by","is_open_access":true,"retracted":false,"peer_reviewed":null,"categories":["2D Materials and Applications"],"details":null,"provenance":"openalex","attribution":"Abstract of \"Prediction of intrinsic two-dimensional ferroelectrics in In2Se3 and other III2-VI3 van der Waals materials\" by Wenjun Ding, Jianbao Zhu, Zhe Wang et al., https://doi.org/10.1038/ncomms14956, used under its Creative Commons Attribution license (CC-BY); markup removed, otherwise unmodified.","topics":[{"slug":"2d-materials","name":"2D Materials & Van der Waals Heterostructures","domain_slug":"materials"}],"cited_in_dossiers":[{"slug":"2d-materials","title":"2D Materials & Van der Waals Heterostructures: State of the Field (October 2026)","url":"https://space-kitty.com/dossiers/2d-materials"}]}
