Protective layer enhanced the stability and superconductivity of tailored antimonene bilayer

Jun-Jie Zhang, Yang Zhang, Shuai Dong

For two-dimensional superconductors, the high stability in ambient conditions is critical for experiments and applications. Few-layer antimonene can be non-degradative over a coupl…

Unusual Ferroelectricity of Trans-Unitcell Ion-Displacement and Multiferroic Soliton in Sodium and Potassium Hydroxides

Yangyang Ren, Shuai Dong, Menghao Wu

We show the first-principles evidence of a hitherto unreported type of ferroelectricity with ultra-long ion-displacement in sodium and potassium hydroxides. Even a small amount of…

Possible origin of the absence of magnetic order in LiOsO: Spin-orbit coupling controlled ground state

Y. Zhang, J. J. Gong, C. F. Li +4

LiOsO is the first experimentally confirmed polar metal with ferroelectric-like distortion. One puzzling experimental fact is its paramagnetic state down to very low temperatur…
