Robustness of type-II Dirac cones in biphenylene-based structures
L. L. Lage, O. Arroyo-Gascón, Leonor Chico +1
The electronic properties of one- and two-dimensional biphenylene-based systems, such as nanoribbons and bilayers, are studied within a unified approach. Besides the bilayer with d…
Fractional corner charges in threefold-symmetric two-dimensional materials with fragile topology
Olga Arroyo-Gascón, Sergio Bravo, Leonor Chico +1
We perform a systematic study of the signatures of fragile topology in over 50 nonmagnetic two-dimensional materials with formula AB, belonging to space group -. Using…
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…
Persistence of symmetry-protected Dirac points at the surface of the topological crystalline insulator SnTe upon impurity doping
Olga Arroyo-Gascón, Yuriko Baba, Jorge I. Cerdá +4
We investigate the effect of a non-magnetic donor impurity located at the surface of the SnTe topological crystalline insulator. In particular, the changes on the surface states du…
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…
