Decoding the conductance of disordered nanostructures: a quantum inverse problem
S. Mukim, J. O'Brien, M. Abarashi +2
Obtaining conductance spectra for a concentration of disordered impurities distributed over a nanoscale device with sensing capabilities is a well-defined problem. However, to do t…
The influence of Gaussian strain on sublattice selectivity of impurities in graphene
James A Lawlor, Claudia G Rocha, Vanessa Torres +2
Among the different strategies used to induce the opening of a band gap in graphene, one common practice is through chemical doping. While a gap may me opened in this way, disorder…
Topological Signatures in the Electronic Structure of Graphene Spirals
Stas M. Avdoshenko, Pekka Koskinen, Haldun Sevincli +2
Topology is familiar mostly from mathematics, but also natural sciences have found its concepts useful. Those concepts have been used to explain several natural phenomena in biolog…
Enhancing single-parameter quantum charge pumping in carbon-based devices
L. E. F. Foa Torres, H. L. Calvo, C. G. Rocha +1
We present a theoretical study of quantum charge pumping with a single ac gate applied to graphene nanoribbons and carbon nanotubes operating with low resistance contacts. By combi…
Mechanically-Induced Transport Switching Effect in Graphene-based Nanojunctions
T. Kawai, M. Poetschke, Y. Miyamoto +3
We report a theoretical study suggesting a novel type of electronic switching effect, driven by the geometrical reconstruction of nanoscale graphene-based junctions. We considered…
A computationally efficient method for calculating the maximum conductance of disordered networks: Application to 1-dimensional conductors
Luiz F. C. Pereira, C. G. Rocha, A. Latge +1
Random networks of carbon nanotubes and metallic nanowires have shown to be very useful in the production of transparent, conducting films. The electronic transport on the film dep…
