“…The presence of inherent mirror symmetry breaking endows Janus 2D materials with some fascinating properties, 5,29,30 such as surface work function difference, intrinsic dipole moment, internal out-of-plane electric field, Rashba effect, [31][32][33] and different surface catalytic properties. 34 Excitingly, Janus 2D materials have been fabricated experimentally, 35 which motivates us to probe more excellent Janus 2D materials.…”

A class of septuple-atomic-layer two-dimensional (2D) materials, MA2Z4, is sought as an alternative to 2D hexagonal transition metal dichalcogenides in the fields of valleytronics and spintronics. In these materials, the structural symmetry can be varied by changing the stacking of its three parts in the monolayer. We use first-principles calculations to show that in the Janus monolayer WSiGeZ4 (Z = N, P, As), Berry curvature and the Rashba effect are enhanced by modifying the stacking orders. The intrinsic electric field and composition of the d orbitals play a dominant role in determining these properties. Berry curvature is strengthened by up to 300% compared to its ground state through symmetry control, along with a significant increment in the Rashba coefficient. Moreover, monolayers WSiGeP4 and WSiGeAs4 have multiple valleys, implying another valley-dimension. The interesting spin-valley physics tunability in septuple-atomic-layer 2D materials suggests their exceptional potential for spintronic and valleytronic applications.

“…This appearance indicates that the I-5p z orbital plays an important role for the Rashba effect, which is similar to the d z 2 controlling Rashba coupling in the 1T-phase Janus WSSe monolayers. 44 However, in the VBM of (MV)SbI 3 Cl 2 , the Rashba constant and the z -direction strain are negatively correlated. The contributions of Sb-5p z and I-5p z to the VBM gradually decrease, leading to the reduction of p–p orbital coupling between Sb and I atoms in the z direction as shown in Fig.…”
