DOI: 10.1016/j.actamat.2019.01.005
Abstract: Abstract Domain behavior of (111)- oriented perovskite ferroelectric films is significantly different from (001)-/(101)- oriented ones, resulting in enhancing property responses such as a superior susceptibility and a reduced coercive field. However, the domain structures… read more here.

DOI: 10.1016/j.ensm.2021.04.010
Abstract: Abstract Well-crystallized perovskite ferroelectric films usually display a bulk-like polarization response (P) under an external electric field (E), i.e., a large P-E hysteresis loop featuring a sizable remnant polarization and an early polarization saturation. Such… read more here.
