A one-dimensional organic-inorganic hybrid ferroelectric exhibiting dielectric-optical duple switch

A one-dimensional organic-inorganic hybrid, (C 4 H 8 NH 2 ) 2 [BiCl 5 ] (C 4 H 8 NH 2 + = pyrrolidinium), exhibiting a reversible ferroelectric phase transition accompany by switchable dielectric and quadratic nonlinear optical properties. Theoretical study discloses the ferroelectricity originating from...
