Two-dimensional half-metallicity in transition metal atoms decorated Cr2Ge2Te6

As one of the first experimentally found and naturally stable two-dimensional (2D) ferromagnetic materials, monolayer Cr 2 Ge Te 6 has garnered great interest due to its potential hires in electronics spintronics. Yet, Curie temperature is lower than ambient temperature, severely restricting creation valuable devices. Using first-principle calculations, we explored how adsorption 3 d transition metals affects electronic magnetic properties (from Sc Zn). Our findings indicate that depending on be adsorbed, system may adjusted from semiconductor metal/half-metal. We Ti Fe leads a transformation metal. While @Sc, V, Co, Ni, Cu, absorption realizes changes half Moreover, modify moment adsorbed enhance stability . Furthermore, are able modulate half-metallic @Mn by means electric fields. Hence, viable method for modulating 2D ferromagnets, paving door future development nano-electronic spintronic devices with enhanced performance materials.
