WebJan 26, 2024 · Here, we report on a technology in which anisotropic PhPs supported by biaxial vdW slabs are actively tuned by simply gating an integrated graphene layer. Excitingly, we predict active tuning of optical topological transitions, which enable controlling the canalization of PhPs along different in-plane directions in twisted heterostructures. WebGraphene is a single layer of carbon atoms that are bound together by overlapping sp2 hybrid bonds. The remarkable attributes of graphene come from the 2p orbitals, which …
