Electronic localization at mesoscopic length scales: different definitions of localization and contact effects in a heuristic DNA model
C. J. Páez, P. A. Schulz
In this work we investigate the electronic transport along model DNA molecules using an effective tight-binding approach that includes the backbone on site energies. The localizati…
Robust signatures in the current-voltage characteristics of DNA molecules oriented between two graphene nanoribbon electrodes
Carlos J. Páez, Peter A. Schulz, Neil Wilson +1
In this work we numerically calculate the electric current through three kinds of DNA sequences (telomeric, λ-DNA, and p53-DNA) described by different heuristic models. A bias volt…
Graphene in the Quantum Hall Regime: Effects of Vacancies, Sublattice Polarization and Disorder
Ana L. C. Pereira, Peter A. Schulz
We investigate the effects of vacancies, disorder and sublattice polarization on the electronic properties of a monolayer graphene in the quantum Hall regime. Energy spectra as a f…
Valley polarization effects on the localization in graphene Landau levels
Ana L. C. Pereira, P. A. Schulz
Effects of disorder and valley polarization in graphene are investigated in the quantum Hall regime. We find anomalous localization properties for the lowest Landau level (LL), whe…
Double chains with base pairing: delocalization irrespective to DNA sequencing
R. A. Caetano, P. A. Schulz
The question of whether DNA is intrinsically conducting or not is still a challenge. The ongoing debate on DNA molecules as an electronic material has so far underestimated a key d…
Hidden Scaling in the Quantum Hall Metal-Insulator Transition
L. Moriconi, Ana L. C. Pereira, P. A. Schulz
Scaling properties of the quantum Hall metal-insulator transition are severely affected by finite size effects in small systems. Surprisingly, despite the narrow spatial range wher…
