Bi vacancy formation in BiFeO3 epitaxial thin films under compressive (001)-strain from first principles
(Peer reviewed; Journal article, 2019)Point defects in BiFeO3 affect both structural and functional properties. To elucidate the role of single Bi vacancies and Bi–O vacancy pairs we investigate their stability and effect on structural and ferroelectric ... -
Ferroelectric and dielectric properties of Ca2+-doped and Ca2+-Ti4+ co-doped K0.5Na0.5NbO3 thin films
(Journal article; Peer reviewed, 2020)Chemical solution deposition (CSD) of K0.5Na0.5NbO3 (KNN) thin films on silicon-based substrates is an interesting technology for fabrication of lead-free ferroelectric thin films. Here, we report on improved ferroelectric ... -
Investigation of factors affecting the stability of compounds formed by isovalent substitution in layered oxychalcogenides, leading to identification of Ba3Sc2O5Cu2Se2, Ba3Y2O5Cu2S2, Ba3Sc2O5Ag2Se2 and Ba3In2O5Ag2Se2
(Peer reviewed; Journal article, 2022)Four novel compositions containing chalcogenide layers, adopting the Ba3M2O5M02Ch2 layered structure have been identified: Ba3Sc2O5Cu2Se2, Ba3Y2O5Cu2S2, Ba3Sc2O5Ag2Se2 and Ba3In2O5Ag2Se2. A comprehensive comparison of ... -
Super-coercive electric field hysteresis in ferroelectric plastic crystal tetramethylammonium bromotrichloroferrate(III)
(Peer reviewed; Journal article, 2020)Ionic plastic crystals are part of an emerging class of hybrid organic–inorganic ferroelectrics. The combination of low dielectric constants (<20), strong piezoelectric coefficients (>100 pC N−1) and low temperature synthesis ...
