Flat bands in ultra-wide gap two-dimensional germanium dioxide
Rafael Franco Ribeiro Reis, Gabriel Elyas Gama Araujo, Danilo Kuritza +3
We employ first principles density-functional theory (DFT) and the Bethe-Salpeter equation (BSE) in the framework of tight-binding based maximally localized Wannier functions (MLWF…
Electronic and optical and topological properties of defects in bismuthene
Gabriel Elyas Gama Araujo, Andreia Luisa da Rosa, Alexandre Cavalheiro Dias +1
In this work we use first principles density-functional theory and Bethe-Salpeter equation together with tight-binding based maximally localized wannier functions (MLWF-TB) to inve…
Electronic and optical properties of two-dimensional flat band triphosphides
Gabriel Elyas Gama Araujo, Lucca Moraes Gomes, Dominike Pacine de Andrade Deus +2
In this work we use first-principles density-functional theory (DFT) calculations combined with the maximally localized Wannier function tight binding Hamiltonian (MLWF-TB) and Bet…
