Polarization-tuneable excitonic spectral features in the optoelectronic response of atomically thin ReS2
Daniel Vaquero, Olga Arroyo-Gascón, Juan Salvador-Sánchez +7
The low crystal symmetry of rhenium disulphide (ReS2) leads to the emergence of dichroic optical and optoelectronic response, absent in other layered transition metal dichalcogenid…
Universality of moiré physics in collapsed chiral carbon nanotubes
Olga Arroyo-Gascón, Ricardo Fernández-Perea, Eric Suárez Morell +2
We report the existence of moiré patterns and magic angle physics in all families of chiral collapsed carbon nanotubes. A detailed study of the electronic structure of all types of…
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…
One-dimensional moiré superlattices and flat bands in collapsed chiral carbon nanotubes
Olga Arroyo-Gascón, Ricardo Fernández-Perea, Eric Suárez Morell +2
We demonstrate that one-dimensional moiré patterns, analogous to those found in twisted bilayer graphene, can arise in collapsed chiral carbon nanotubes. Resorting to a combination…
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…
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…
