Bilayer Stacking Ferrovalley without Breaking Time-Reversal Symmetry
Guoliang Yu, Junyi Ji, Changsong Xu +1
Non-volatile manipulation of valley polarization in solids has long been desired for valleytronics applications but remains challenging. Here, we propose a novel strategy for non-v…
Unconventional Ferroelectricity in Violation with Neumann's Principle
Junyi Ji, Guoliang Yu, Changsong Xu +1
The physical properties of crystals are governed by their symmetry according to Neumann's principle. However, we present a case that contradicts this principle wherein the polariza…
General Theory for Bilayer Stacking Ferroelectricity
Junyi Ji, Changsong Xu, H. J. Xiang
Two-dimensional (2D) ferroelectrics, which is rare in nature, enable high-density non-volatile memory with low energy consumption. Here, we propose a theory of bilayer stacking fer…
Two-Dimensional Organic-Inorganic Room-Temperature Multiferroic
Yali Yang, Junyi Ji, Junsheng Feng +3
Organic-inorganic multiferroics are promising for the next generation of electronic devices. To date, dozens of organic-inorganic multiferroics have been reported; however, most of…
Tunable spin textures in polar antiferromagnetic hybrid organic inorganic perovskites by electric and magnetic fields
Feng Lou, Teng Gu, Junyi Ji +3
The hybrid organic inorganic perovskites (HOIPs) have attracted much attention for their potential applications as novel optoelectronic devices. Remarkably, the Rashba band splitti…
Band splitting with vanishing spin polarizations in noncentrosymmetric crystals
Kai Liu, Wei Luo, Junyi Ji +3
The Dresselhaus and Rashba effects are well-known phenomena in solid-state physics, in which spin-orbit coupling (SOC) splits spin-up and spin-down energy bands of nonmagnetic non-…
