Tunable Dual-Type Weyl Points in Dirac-Weyl Semimetal CaAgBi
Shenghao Huang, Heng Gao, Hongfei Wang +1
Dirac-Weyl semimetals host both Dirac and Weyl fermions and the exploration of material candidates with tunable topological properties is essential to realize topological spintroni…
Probing the Chirality of Trigonal Selenium and Tellurium by Spin and Orbital Hall Effects
Yuting Xiong, Yingjie Hu, Wei Ren +1
Chiral crystals exhibit enantiomer-dependent transport phenomena that generate pure spin or orbital currents, while the handedness sensitivity of spin and orbital Hall conductiviti…
Polarization Engineering of the Orbital Hall Conductivity in Two-dimensional Ferroelectric Higher-Order Topological Insulator TlS and SnS
YingJie Hu, Heng Gao, Yabei Wu +1
Ferroelectric higher-order topological insulators (HOTIs) exhibit tunable physical properties arising from the interplay between ferroelectric polarization and band topology. This…
Re-refinement of the structure of the planar hexagonal phase of ZnO nanocrystals
Musen Li, Lingyao Zhang, Wei Ren +1
The planar hexagonal phase of ZnO, known as h-ZnO, g-ZnO, α-ZnO, the Bk structure, the 5-5 phase, the α-BN phase, etc., has P63/mmc symmetry and is implicated in ferroelectric sw…
Significance of the dispersion force for ferroelectric switching in ZnO and related materials
Lingyao Zhang, Musen Li, Nisha Metha +3
Wurtzite-ZnO is a wide-bandgap polar material with a ferroelectric-switching barrier that is too high to utilize, but the barrier can be reduced and switching observed in substitut…
