Tunable topology and berry curvature dipole in transition metal dichalcogenide Janus monolayers

Tunable topology and berry curvature dipole in transition metal dichalcogenide Janus monolayers

Janus transition metal dichalcogenides, with intrinsic mirror asymmetry, exhibit a wide array of interesting properties. In this work, we study Janus monolayers derived from WTe _2 using first-principles and tight-binding calculations. We discover that WSeTe and WSTe are topologically trivial, in co...
