Proximity Ferroelectricity Driven by Mobile High-Miller-Index Domain Walls
Changming Ke, Shi Liu
Wurtzite ferroelectrics such as scandium-doped aluminum nitride (AlScN) are promising for next-generation memory because of their compatibility with semiconductor processes and str…
Topological Control of Transition Metal Networks for Reversible High-Capacity Li-rich Cathodes
Changming Ke, Yudi Yang, Minjun Wang +2
Developing high-energy-density batteries is essential for advancing sustainable energy technologies. However, leading cathode materials such as Li-rich oxides, including LiMnO$…
Superlubric Motion of Wave-like Domain Walls in Sliding Ferroelectrics
Changming Ke, Fucai Liu, Shi Liu
Sliding ferroelectrics constructed from stacked nonpolar monolayers enable out-of-plane polarization in two dimensions with exceptional properties, including ultrafast switching sp…
Sliding-Reversible Bandgap Modulation in Irreversible Asymmetric Multilayers
Changming Ke, Yudi Yang, Zhuang Qian +1
The electronic bandgap of a material is often fixed after fabrication. The capability to realize on-demand and non-volatile control over the bandgap will unlock exciting opportunit…
