Impact of impurities on the topological boundaries and edge state localization in a staggered chain of atoms: SSH model and its topoelectrical circuit realization
Julio César Pérez-Pedraza, José Eduardo Barrios-Vargas, Alfredo Raya
We study the Su-Schrieffer-Hegger model, perhaps the simplest realization of a topological insulator, in the presence of an embedded impurity superlattice. We consider the impact o…
Linear Scaling Quantum Transport Methodologies
Zheyong Fan, Jose Hugo Garcia, Aron W. Cummings +5
In recent years, predictive computational modeling has become a cornerstone for the study of fundamental electronic, optical, and thermal properties in complex forms of condensed m…
Grain boundary-induced variability of charge transport in hydrogenated polycrystalline graphene
Jose E. Barrios Vargas, Jesper T. Falkenberg, David Soriano +3
Chemical functionalization has proven to be a promising means of tailoring the unique properties of graphene. For example, hydrogenation can yield a variety of interesting effects,…
Fingerprints of a position-dependent Fermi velocity on scanning tunnelling spectra of strained graphene
M. Oliva-Leyva, J. E. Barrios-Vargas, Chumin Wang
Nonuniform strain in graphene induces a position dependence of the Fermi velocity, as recently demonstrated by scanning tunnelling spectroscopy experiments. In this work, we study…
