The switchable quantum anomalous Hall effect and altermagnetism in Janus monolayer and bilayer V <sub>2</sub> WS <sub>2</sub> Se <sub>2</sub>
First-principles calculations reveal the dual functionality of bilayer V 2 WS 2 Se 2 . Interlayer sliding switches it between an altermagnetic semiconductor and a quantum anomalous Hall insulator, offering a promising platform for spintronic devices.
