摘　　要：Ferroelectric materials are typically made up of various elements.By introducing atomic displacements,[1]such as octahedral tilts/rotations[2,3]or interlayer sliding,[4–7]the positive and negative charge centers can be separated,resulting in spontaneous polarization.Due to their homogeneity,it is difficult to achieve ferroelectricity in elemental materials where opposite charge centers must be generated.
