Dynamical evolution of the 2D/3D interface: a hidden driver behind perovskite solar cell instability

January 3, 2020
Author(s)
Lee J. Richter, Ahmad R. Kirmani, Albertus A. Sutano, Nikita Drigo, Ines G. Benito, Valentine I. Queloz, Kyung T. Cho, Pascal A. Schouwink, Mohammad K. Nazeeruddin, Giulia Grancini, Sanghyun Paek
… in the 3D cage move towards the 2D layer, which acts as an ion scavenger. If structurally stable, the 2D layer physically blocks the ion movement at the interface boosting the device stability. …

Switching Between Giant Positive and Negative Thermal Expansions of a YFe(CN) 6 -Based Prussian Blue Analogue Induced by Guest Species

Qilong Gao, Jun Chen, Qiang Sun, Dahu Chang, Qingzhen Huang, Hui Wu, Andrea Sanson, Ruggero Milazzo, He Zhu, Qiang Li, Zhanning Liu, Jinxia Deng, Xianran Xing
The control of thermal expansion of solid compounds is intriguing but remains challenge. In this study, we investigate the effect of guests on the thermal expansion of open-framework structures. It is interesting to observe that the presence of guest ions

Ising-Like Antiferromagnetism on the Octahedral Sublattice of a Cobalt-Containing Garnet and the Potential for Quantum Critically

April 14, 2017
Author(s)
Abbey J. Neer, Joanna Milam-Guerrero, Justin E. So, Brent C. Melot, Kate Ross, Zeric Hulvey, Craig Brown, Alexey A. Sokol, David O. Scanlon
In this letter, we report the observation of quasi-one-dimensional magnetism in the garnet CaY 2Co 2Ge 3O 12. Using low-temperature powder neutron diffraction and symmetry analysis, we identify a magnetic structure consisting of chain-like motifs oriented

Neutron Scattering Studies of LiCoPO 4 & LiMnPO 4

June 9, 2009
Author(s)
W. Tian, Jiying Li, Haifeng Li, Jeffrey W. Lynn, J. L. Zarestky, David Vaknin
… nearest neighbor magnetic exchange interactions and single ion anisotropy. The INS results indicate that LiMnPO 4 behaves like a quasi-2D material and that the single ion anisotropy in LiCoPO 4 is comparable to the …
