Characterization of hard piezoelectric lead-free ceramics. [PDF]
IEEE Trans Ultrason Ferroelectr Freq Control, 2009 K4CuNb8O23 doped K(0.45)Na(0.55)NbO3(KNNKCN) ferroelectric ceramics were found to exhibit asymmetrical polarization hysteresis loops, related to the development of an internal bias field. The internal bias field is believed to be the result of defect dipoles of acceptor ions and oxygen vacancies, which lead to piezoelectric "hardening" effect, by ...
