Topological bands in the PdSe pentagonal monolayer
Sergio Bravo, M. Pacheco, J. D. Correa +1
The electronic structure of monolayer pentagonal palladium diselenide (PdSe2) is analyzed from the topological band theory perspective. Employing first-principles calculations, eff…
Twisted bilayer blue phosphorene: A direct band gap semiconductor
D. A. Ospina, C. A. Duque, J. D. Correa +1
We report that two rotated layers of blue phosphorene behave as a direct band gap semiconductor. The optical spectrum shows absorption peaks in the visible region of the spectrum a…
Ab-initio analysis of superstructures revealed by STM on bilayer graphene
E. Cisternas, J. D. Correa
In this work we performed density functional theory calculations for a twisted bilayer graphene (BLG). Several conmensurable rotation angles were analyzed and for each one a consta…
Flat Bands in Slightly Twisted Bilayer Graphene
E. Suárez Morell, J. D. Correa, P. Vargas +2
The bands of graphite are extremely sensitive to topological defects which modify the electronic structure. In this paper we found non-dispersive flat bands no farther than 10 meV…
