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…
Two-dimensional Topological Semimetals Protected by Symmorphic Symmetries
Wei Luo, Junyi Ji, Jinlian Lu +2
Two-dimensional (2D) band crossing semimetals (BCSMs) could be used to build a range of novel nanoscale devices such as superlenses and transistors. We find that symmorphic symmetr…
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-…
