  • SnTiO3 material, method of preparation thereof, use thereof as ferroelectric material and device comprising a ferroelectric material
    Patent number: 11787702
    Abstract: The present invention relates to a material of the formula SnTiO3 having a crystal structure comprised of layers, wherein the layers comprise Sn(II) ions, Ti(IV) ions and edge-sharing O6-octahedra, the edge-sharing O6-octahedra form a sub-layer, the Ti(IV) ions are located within ? of the edge-sharing O6-octahedra, thus forming edge-sharing TiO6-octahedra, the edge-sharing TiO6-octahedra form a honeycomb structure within the sub-layer, the honeycomb structure comprising hexagons with Ti(IV)-vacancies within the hexagons, the Sn(II) ions are located above and below the Ti(IV)-vacancies with respect to the sub-layer, the Ti(IV) ions are optionally substituted with M, M is one or more elements selected from Group 4 and Group 14 elements, and the crystal structure satisfies at least one of the following features (i) and (ii): (i) the Sn(II) ions have a tetrahedral coordination sphere involving three O ions of the layer and the electron lone pair of the Sn(II) ions which is situated at an apical position relative
    Type: Grant
