Permanent ferroelectric retention of BiFeO3 mesocrystal (2016)
Journal Article
Hsieh, Y., Xue, F., Yang, T., Liu, H., Zhu, Y., Chen, Y., …Chu, Y. (2016). Permanent ferroelectric retention of BiFeO3 mesocrystal. Nature Communications, 7, Article 13199. https://doi.org/10.1038/ncomms13199

Non-volatile electronic devices based on magnetoelectric multiferroics have triggered new possibilities of outperforming conventional devices for applications. However, ferroelectric reliability issues, such as imprint, retention and fatigue, must be... Read More about Permanent ferroelectric retention of BiFeO3 mesocrystal.

A Metal-Insulator Transition of the Buried MnO2 Monolayer in Complex Oxide Heterostructure (2016)
Journal Article
Liu, H., Lin, J., Fang, Y., Wang, J., Huang, B., Gao, X., …Chu, Y. (2016). A Metal-Insulator Transition of the Buried MnO2 Monolayer in Complex Oxide Heterostructure. Advanced Materials, 28(41), 9142-9151. https://doi.org/10.1002/adma.201602281

A novel artificially created MnO2 monolayer system is demonstrated in atomically controlled epitaxial perovskite heterostructures. With careful design of different electrostatic boundary conditions, a magnetic transition as well as a metal–insulator...

The control of magnetism via an electric field has attracted substantial attention because of potential applications in magnetoelectronics, spintronics and high-frequency devices. In this study, we demonstrate a new approach to enhance and control th... Read More about Electrically enhanced magnetization in highly strained BiFeO3 films.

Observation of a three-dimensional quasi-long-range electronic supermodulation in YBa2Cu3O7-x/La0. 7Ca0. 3MnO3 heterostructures (2016)
Journal Article
He, J., Shafer, P., Mion, T. R., Tra, V. T., He, Q., Kong, J., …He, R. (2016). Observation of a three-dimensional quasi-long-range electronic supermodulation in YBa2Cu3O7-x/La0. 7Ca0. 3MnO3 heterostructures. Nature Communications, 7, Article 10852. https://doi.org/10.1038/ncomms10852

Recent developments in high-temperature superconductivity highlight a generic tendency of the cuprates to develop competing electronic (charge) supermodulations. While coupled with the lattice and showing different characteristics in different materi...
