KPROJ: A Program for Unfolding Electronic and Phononic Bands
Jiaxin Chen, M. Weinert, Mingxing Chen
We introduce a program named KPROJ that unfolds the electronic and phononic band structure of materials modeled by supercells. The program is based on the -projection m…

Combining intrinsic and sliding-induced polarizations for multistates in two dimensional ferroelectrics
Chuhan Tang, Zhiqiang Tian, Tao Ouyang +2
Going beyond the bistability paradigm of the charge polarizations in ferroelectrics is highly desired for ferroelectric (FE) memory devices toward ultra-high-density information st…
