Graphene, a two dimensional (2D) crystal of carbon atoms, is an outstanding spin transport medium because of its inert nature to electron’s spin. Inspiredby this, recently the PI’s research has demonstrated high spintronic performanceinlarge scale chemical vapor deposited (CVD) graphene, demonstrating its true practical potential. In addition to graphene, semiconducting 2D crystals such as MoS2, MoSe2, and black phosphorus have also emerged as promising materials for spin modulation effects. In this proposal, going beyond conventional studies and the present state-of-the-art, and using these two crystals and nanomagnetic circuits, the PI’s aims to innovate and investigate next generation spintronic devices for future ultralow power electronics. Here, hesetstwo goals: first, to explore spin transport in CVD graphene on novel flexible substrates. Second, to investigate CVDgraphene spin circuitsfor spin manipulation and spintorque effects.Spin manipulation will be achieved by introducing MoSe2crystals within CVD graphene channels. Spintorque effects (in CVD graphene channels) will be explored throughpatterned channelsto unravel spin current interactions,switching nanomagnets and controlled positioning of domain walls.The proposedexperimentswould lead to unexploredfundamental physics of these new systems, results would pave the way for future advanced flexible spin circuits. Furthermore, the optimized innovative designs are anticipated to generateIPrights.
