摘要
Materials exhibiting the quantum anomalous Hall effect (QAHE), and thus dissipationless chiral edge states, would be terrific for ultralow-power spintronic devices. Realizing a room-temperature ferromagnetic semiconductor and room-temperature QAHE have both been ongoing grand challenges. This density-functional study reveals that bulk PdBr${}_{3}$ and monolayer PtBr${}_{3}$ are promising candidates to address both challenges at once. The results offer guidance for developing a material platform for ultraefficient topological spintronic devices.
