The group-IV monochalcogenide, with an anisotropic puckered structure and an intrinsic in-plane polarization at room temperature, manifests itself as a promising candidate with coupled ferroelectric and ferroelastic order as the basis for multiferroic behavior. Unlike the intrinsic centrosymmetric AB stacking, we demonstrate a multiferroic phase of tin selenide (SnSe), where the inversion symmetry breaking is maintained in AA-stacked multilayers over a wide range of thicknesses. We observe that an interlayer-sliding-induced out-of-plane (OOP) ferroelectric polarization couples with the in-plane (IP) one, making it possible to control out-of-plane polarization via in-plane electric field and vice versa. Notably, thickness scaling yields a sub-0.3 V ferroelectric switching, which promises future low-power-consumption applications. Furthermore, coexisting armchair- and zigzag-like structural domains are imaged under electron microscopy, providing experimental evidence for the degenerate ferroelastic ground states theoretically predicted. Non-centrosymmetric SnSe, as the first layered multiferroic at room temperature, provides a novel platform not only to explore the interactions between elementary excitations with controlled symmetries, but also to efficiently tune the device performance via external electric and mechanical stress. description_type: abstract lang: und ## Creator - name: Rui Chen role: author - name: Fanhao Meng role: author - name: Hongrui Zhang role: author - name: Yuzi Liu role: author - name: Shancheng Yan role: author - name: Xilong Xu role: author - name: Linghan Zhu role: author - name: Jiazhen Chen role: author - name: Tao Zhou role: author - name: Jingcheng Zhou role: author - name: Fuyi Yang role: author - name: Penghong Ci role: author - name: Xiaoxi Huang role: author - name: Xianzhe Chen role: author - name: Tiancheng Zhang role: author - name: Yuhang Cai role: author - name: Kaichen Dong role: author - name: Yin Liu role: author - name: Kenji Watanabe role: author orcid: https://orcid.org/0000-0003-3701-8119 organization: National Institute for Materials Science - name: Takashi Taniguchi role: author orcid: https://orcid.org/0000-0002-1467-3105 organization: National Institute for Materials Science - name: Chia-Ching Lin role: author - name: Ashish Verma Penumatcha role: author - name: Ian Young role: author - name: Emory Chan role: author - name: Junqiao Wu role: author - name: Li Yang role: author - name: Ramamoorthy Ramesh role: author - name: Jie Yao role: author ## Contact agent ## Publisher organization: Springer Science and Business Media LLC ## Managing organization ## Keyword - subject: multiferroicity schema: not_defined - subject: 'van der Waals semiconductors
