Rippled Moire Superlattices for Decoupled Ferroelectric Bits
Di Fan, Changming Ke, Shi Liu
Symmetry considerations suggest that moire superlattices formed by twisted two-dimensional materials should preserve overall inversion symmetry. However, experiments consistently r…

Unexpected Density Functional Dependence of the Antipolar Phase in HfO
Di Fan, Tianyuan Zhu, Shi Liu
The antipolar phase of HfO has been suggested to play an important role in the phase transition and polarization switching mechanisms in ferroelectric hafnia. In this st…
