Effects of lattice geometry on the dynamic properties of dipolar-coupled magnetic nanodisk arrays
Slöetjes, Samuel Dingeman; Digernes, Einar; Klewe, Christoph; Shafer, Padraic; Li, Qian; Yang, M.; Qiu, Z.Q.; N'diaye, Alpha T; Arenholz, Elke; Folven, Erik; Grepstad, Jostein (Journal article; Peer reviewed, 2019)We have studied the impact of lattice geometry on the dynamic properties of close-spaced arrays of circular nanomagnets, also known as magnonic crystals. To this end, we prepared 2D nanomagnet arrays with both square and ... -

Zheng, Ya-Shan; Zhang, Min; Li, Qian; Zhu, Yi-An; Sui, Zhi-Jun; Chen, De; Zhou, Xing-Gui (Journal article; Peer reviewed, 2019)Understanding the oxygen transport behavior in perovskites is of central importance for tailoring their physical and chemical properties to various practical applications. In this contribution, periodic DFT+U calculations ... -
Insights into hydrogen transport behavior on perovskite surfaces: Transition from the Grotthuss mechanism to the “vehicle” mechanism
Li, Qian; Yin, Qiang; Zheng, Ya-Shan; Sui, Zhi Jun; Zhou, Xinggui; Chen, De; Zhu, Yi-an (Journal article; Peer reviewed, 2019)Hydrogen transport on transition-metal oxides is a shared process in many important physical and chemical changes of interest. In this work, DFT + U calculations have been carried out to explore the mechanism for hydrogen ... -
Structural stability of Lanthanum-based oxygen-deficient perovskites in redox catalysis: A density functional theory study
Li, Qian; Deng, Yun-Xiang; Zhu, Yi-An; Li, Yang; Sui, Zhi Jun; Chen, De; Yuan, Wei-Kang (Journal article; Peer reviewed, 2018)Periodic density functional theory calculations have been performed to examine the effect of oxygen deficiency on the structural stability of Lanthanum-based perovskites (LaMO3), where on-site Coulomb interactions have ...
