Abstract
A comprehensive structural analysis of novel 2D-Cr2Ge2Te6 and its heterostructure with graphene was performed through density functional theory approach with GGA + U exchange correlation functionals. Our first-principles calculations indicate that pristine 2D-Cr2Ge2Te6 emerges out to be a semiconductor, whereas its heterostructure with graphene is metallic in nature. The combination of 2D-Cr2Ge2Te6 with graphene facilitates the manipulation of charge and spin, paving the way for novel applications in spintronics, valleytronics, and memory-based devices. The interplay between the magnetic order of Cr2Ge2Te6 and the high carrier mobility of graphene can inspire researchers working in this direction with an idea to enhance device performance, including improved spin injection and tuneable optoelectronic response.
