[Bi2O2] 2+ in BiOCl, arranged in a repeating pattern along the c-direction, exhibit an anisotropy with spontaneous polarization . This characteristic is responsible for the ferroelectricity observed in the BiOCl lattice . Nevertheless, ferroelectric materials play a crucial role in various technological applications such as nonvolatile memories , field-effect transistors (FET) , solar cells , sensors , photonics devices , and more . These materials are known for their stable and switchable spontaneous polarization, which can be reversed by an external electric field.
