| contents | This 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. Additionally, a significant evolution in fatigue behavior is captured, transitioning from hard breakdown to ferroelectricity loss at cryogenic temperatures. These findings unlock the feasibility for wurtzite ferroelectrics to advance wide temperature non-volatile memory. |
