Yánez-Parreño, Alexander Vera, Sandra Santhosh, Chengye Dong et al.arXiv preprint·2025·10.1103/fwrg-3dr2·arXiv:2501.07699AbstractWe report charge to spin conversion in a hybrid heterostructure comprised of atomically thin bismuth (Bi) confined between a silicon carbide (SiC) substrate and epitaxial graphene (EG). We confirm composition, dimensionality, and a 96.5% intercalation coverage using X-ray photoelectron spectroscopy, scanning transmission microscopy, low energy electron diffraction, and Raman spectroscopy. Electrical transport measurements show signs of weak antilocalization in the heterostructure, consistent with spin-orbit coupling in this hybrid heterostructure. Spin torque ferromagnetic resonance measurements in permalloy/EG/2D-Bi heterostructures probe charge-to-spin conversion, revealing an in-plane polarization of the spin current, perpendicular to the charge current.Read more
