| Abstract |
Ferroelectricity can be induced in fluorite-structured oxides such as HfO2 and ZrO2, a feature of increasing interest in both academia and industry. Initially, most research focused on solid solution films, but recently, it has been suggested that nanolaminates with independent HfO2 and ZrO2 layers may show electrical and physical properties superior to those of solid solution samples. It was reported that the nanolaminate samples could have remanent polarization higher than that of solid solution film or a wider composition window for robust ferroelectricity compared to the solid solution films. In this review, the existing literature on fluorite-structured nanolaminates is comprehensively reviewed.(Received August 12 2021; Accepted September 1, 2021) |
