Valley polarization in 2D tetragonal altermagnetism
San-Dong Guo Xiao-Shu Guo, Guangzhao Wang
The altermagnetism caused by alternating crystal environment provides a unique opportunity for designing new type of valley polarization. Here, we propose a way to realize valley p…
Large spontaneous valley polarization and anomalous valley Hall effect in antiferromagnetic monolayer
San-Dong Guo, Liguo Zhang, Yiwen Zhang +1
Superior to ferromagnetic (FM) materials, antiferromagnetic (AFM) materials do not have any net magnetic moment and are robust to external magnetic perturbation with ultra-high dyn…
Ultrathick MAN(M'N) Intercalated Monolayers with Sublayer-Protected Fermi Surface Conduction States: Interconnect and Metal Contact Applications
Che Chen Tho, Xukun Feng, Zhuoling Jiang +4
Recent discovery of ultrathick monolayers open up an exciting platform to engineer 2D material properties via intercalation architecture. Here we comput…
How to produce spin-splitting in antiferromagnetic materials
San-Dong Guo, Guang-Zhao Wang, Yee Sin Ang
Antiferromagnetic (AFM) materials have potential advantages for spintronics due to their robustness, ultrafast dynamics, and magnetotransport effects. However, the missing spontane…
Electric-field induced half-metal in monolayer CrSBr
Hao-Tian Guo, San-Dong Guo, Yee Sin Ang
Two-dimensional (2D) half-metallic materials are highly desirable for nanoscale spintronic applications. Here, we propose a new mechanism that can achieve half-metallicity in 2D fe…
Piezoelectric altermagnetism and spin-valley polarization in Janus monolayer
San-Dong Guo, Xiao-Shu Guo, Kai Cheng +2
The altermagnetism can achieve spin-split bands in collinear symmetry-compensated antiferromagnets. Here, we predict altermagnetic order in Janus monolayer with e…
