Bi vacancy formation in BiFeO3 epitaxial thin films under compressive (001)-strain from first principles
Xia, Lu; Tybell, Thomas; Selbach, Sverre Magnus (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 ... -
Composition-Dependent Morphology, Structure, and Catalytical Performance of Nickel–Iron Layered Double Hydroxide as Highly-Efficient and Stable Anode Catalyst in Anion Exchange Membrane Water Electrolysis
Jiang, Wulyu; Faid, Alaa Yahia Abulgheit A.; Gomes, Bruna Ferreira; Galkina, Irina; Xia, Lu; Lobo, Carlos Manuel Silva; Desmau, Morgane; Borowski, Patrick; Hartmann, Heinrich; Maljusch, Artjom; Besmehn, Astrid; Roth, Christina; Sunde, Svein; Lehnert, Werner; Shviro, Meital (Peer reviewed; Journal article, 2022)Water splitting is an environmentally friendly strategy to produce hydrogen but is limited by the oxygen evolution reaction (OER). Therefore, there is an urgent need to develop highly efficient electrocatalysts. Here, NiFe ... -
Electrospun Sandwich-like Structure of PVDF-HFP/Cellulose/PVDF-HFP Membrane for Lithium-Ion Batteries
Zi, Xingfu; Wu, Hongming; Song, Jiling; He, Weidi; Xia, Lu; Guo, Jianbing; Luo, Sihai; Yan, Wei (Peer reviewed; Journal article, 2023)Cellulose membranes have eco-friendly, renewable, and cost-effective features, but they lack satisfactory cycle stability as a sustainable separator for batteries. In this study, a two-step method was employed to prepare ... -
Interactions between point defects and internal interfaces in bismuth ferrite
Xia, Lu (Doctoral theses at NTNU;2019:148, Doctoral thesis, 2019)BiFeO3 (BFO) is the most studied multiferroic material and a promising candidate for future information storage. One challenge for practical applications of this material is a thorough understanding and control of the ...
