In graphene, the structure of the topological bands is reflected in transport experiments, where our numerical models allow us to identify the resonance signatures. We resolve the intrinsic spin-orbit gap [1], the g-factor anisotropic corrections [2, 3], the sub-lattice splitting [4], and the hyperfine-induced splitting in 13C-based graphene [5]. Using Floquet formalism, we find theoretical evidence of a topological transition by illuminating an ideal sample of graphene and the connection between angular momentum and sublattice spin. Finally, we study twisted MoS2 samples, where we resolve low-lying Moir\u00e9 bands near the conduction band.<\/p>\n<p style=\"text-align: left\">Keywords: Twisted bilayer MoS2, Moir\u00e9, superlattices, Mini-bands, Schottky barrier, Resonant Tunneling,<br \/>\nTransition metal dichalcogenides<\/p>\n<p>[1] J.
