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…
Two-dimensional Weyl points and nodal lines in pentagonal materials and their optical response
Sergio Bravo, M. Pacheco, V. Nunez +2
Two-dimensional pentagonal structures based on the Cairo tiling are the basis of a family of layered materials with appealing physical properties. In this work we present a theoret…
Symmetry-protected metallic and topological phases in penta-materials
Sergio Bravo, J. D. Correa, Leonor Chico +1
We analyze the symmetry and topological features of a family of materials closely related to penta-graphene, derived from it by adsorption or substitution of different atoms. Our d…
Equivalence between a topological and non-topological quantum dot - hybrid structures
Ana M. Calle, Mónica Pacheco, Pedro A. Orellana +1
In this work, we demonstrate an equivalence on the single-electron transport properties between systems of different nature, a topological quantum system and a (conventional) non-t…
Tight-binding model for opto-electronic properties of penta-graphene nanostructures
Sergio Bravo, J. D. Correa, Leonor Chico +1
We present a tight-binding parametrization for penta-graphene that correctly describes its electronic band structure and linear optical response. The set of parameters is validated…
Spin and charge caloritronics in bilayer graphene flakes with magnetic contacts
Leonor Chico, P. A. Orellana, L. Rosales +1
We investigate the coupling of spin and thermal currents as a means to rise the thermoelectric efficiency of nanoscale graphene devices. We consider nanostructures composed of over…
