Abstract: The valleytronic properties in monolayer $\mathrm{Mo}{\mathrm{S}}_{2}$ induced by the magnetic proximity effect of an antiferromagnetic CoO(111) substrate have been investigated using density functional theory and Berry curvature calculations. The results show that monolayer $\mathrm{Mo}{\mathrm{S}}_{2}$ can…
