Description
Within the rich landscape of 2D van der Waals heterostructures, proximitised graphene has garnered significant interest as a platform to study emergent spin-dependent phenomena. Here, we apply large-scale Chebyshev spectral methods to simulate the real-space electronic structure of atomic defects in graphene/atomically thin semiconductor heterostructures. This approach allows us to accurately map out the wavevector power spectrum of the quasiparticle interference (QPI) response, and thus determine the impact of proximity-induced Rashba and valley-Zeeman effects. Our study sheds light on the importance of Fermi surface spin-orbit textures in QPI imaging.
