Engineering metal- Dirac bands on the oxidized SiC surface
F. Crasto de Lima, R. H. Miwa
The ability to construct 2D systems, beyond materials natural formation, enriches the search and control capability of new phenomena. For instance, the synthesis of topological lat…
Topological flat band, Dirac fermions and quantum spin Hall phase in 2D Archimedean lattices
F. Crasto de Lima, Gerson J. Ferreira, R. H. Miwa
Materials with designed properties arises in a synergy between theoretical and experimental approaches. In this study we explore the set of Archimedean lattices forming a guidance…
Double flat bands in kagome twisted bilayers
F. Crasto de Lima, R. H. Miwa, E. Suárez Morell
We have studied how a generic bilayer kagome lattice behave upon layer rotation. We employed a Tight Binding model with one orbital per site and found (i) for low rotational angles…
Quantum anomalous Hall effect in metal-bis(dithiolene), magnetic properties, doping and interfacing graphene
F. Crasto de Lima, G. J. Ferreira, R. H. Miwa
The realization of the Quantum anomalous Hall effect (QAHE) in two dimensional (2D) metal organic frameworks (MOFs), (MCS) with M = Mn, Fe, Co, Ru and Rh, has been inve…
