Visualization of domain structure and piezoelectric energy harvesting in a ferroelectric metal–ligand cage

Abstract

The ferroelectric behaviour of an octahedral cage [Ni6(H2O)12(TPTA)8]∙(NO3)12∙37H2O] (1) exhibiting high remnant polarization of 25.31 µC/cm2 is discovered. For the first time, clear domain structures and the characteristic electromechanical responses...
