Two-dimensional intrinsic ferromagnetic semiconductors are expected to stand out in the spintronic field. Recently, monolayer ${\mathrm{VI}}_{3}$ was experimentally synthesized, but weak ferromagnetism and low Curie temperature ${T}_{C}$ limit its potential application. Here we report that Janus structure can elevate 240 K. And discuss reason for high structure, which is lower virtual exchange gap between ${t}_{2g}$ ${e}_{g}$ states of nearest-neighbor V atoms. In addition, be further...
