Cover Story: Can chemical disorder and magnetism coexist in a two-dimensional semiconductor? Semi-hydrogenated SiGe random alloys provide a positive answer. First-principles simulations reveal a robust magnetic semiconducting phase with spin-polarized flat bands, an integer magnetic moment, and remarkable resilience against compositional disorder. The coexistence of tunable electronic and optical properties with intrinsic magnetism establishes hydrogenated 2D SiGe alloys as an attractive platform for next-generation spintronic and magneto-optoelectronic devices. View this paper
