Strong tunability of epitaxial relationship and reconstruction at improper ferroelectric interface
Xin Li, Yu Yun, Guodong Ren +4
The atomic structures at epitaxial film-substrate interfaces determine scalability of thin films and can result in new phenomena. However, it is challenging to control the interfac…

Antiferroelectricity with metastable polar state from Kittel model
Amit Kumar Shah, Xin Li, Guodong Ren +3
We have revisited the Kittel model that describes antiferroelectricity (AFE) in terms of two sublattices of spontaneous polarization with antiparallel couplings. By constructing th…
