Cryogenic Ferroelectric Behavior of Wurtzite Ferroelectrics
IEEE Electron Device LettersThis study presents the first experimental exploration into cryogenic ferroelectric behavior in wurtzite ferroelectrics. A breakdown field (EBD) to coercive field (EC) ratio of 1.8 is achieved even at 4 K, marking the lowest ferroelectric switching temperature reported for wurtzite ferroelectrics.

Ferroelectricity and Self-Polarization in Ultrathin Relaxor Ferroelectric Films [PDF]
Scientific Reports, 2016 AbstractWe report ferroelectricity and self-polarization in the (001) oriented ultrathin relaxor ferroelectric PMN-PT films grown on Nb-SrTiO3, SrRuO3 and La0.7Sr0.3MnO3, respectively. Resistance-voltage measurements and AC impedance analysis suggest that at high temperatures Schottky depletion width in a 4 nm thick PMN-PT film deposited on Nb-SrTiO3 ...
