Superior ferroelectricity and nonlinear optical response in a hybrid germanium iodide hexagonal perovskite

Abstract Abundant chemical diversity and structural tunability make organic–inorganic hybrid perovskites (OIHPs) a rich ore for ferroelectrics. However, compared with their inorganic counterparts such as BaTiO3, their ferroelectric key properties, including large spontaneous polarization (P s), low...
