Planning the electron traffic in semiconductor networks: A mesoscopic analog of the Braess paradox encountered in road networks
S. Huant, S. Baltazar, P. Liu +7
By combining quantum simulations of electron transport and scanning-gate microscopy, we have shown that the current transmitted through a semiconductor two-path rectangular network…
Search for weakly interacting sub-eV particles with the OSQAR laser-based experiment: results and perspectives
P. Pugnat, R. Ballou, M. Schott +19
Recent theoretical and experimental studies highlight the possibility of new fundamental particle physics beyond the Standard Model that can be probed by sub-eV energy experiments.…
Coherent tunnelling across a quantum point contact in the quantum Hall regime
F. Martins, S. Faniel, B. Rosenow +7
The unique properties of quantum Hall devices arise from the ideal one-dimensional edge states that form in a two-dimensional electron system at high magnetic field. Tunnelling bet…
Scanning Gate Spectroscopy of transport across a Quantum Hall Nano-Island
F. Martins, S. Faniel, B. Rosenow +7
We explore transport across an ultra-small Quantum Hall Island (QHI) formed by closed quan- tum Hall edge states and connected to propagating edge channels through tunnel barriers.…
Broken Symmetries, Zero-Energy Modes, and Quantum Transport in Disordered Graphene: From Supermetallic to Insulating Regimes
Alessandro Cresti, Frank Ortmann, Thibaud Louvet +2
The role of defect-induced zero-energy modes on charge transport in graphene is investigated using Kubo and Landauer transport calculations. By tuning the density of random distrib…
Atomistic Boron-Doped Graphene Field Effect Transistors: A Route towards Unipolar Characteristics
Paolo Marconcini, Alessandro Cresti, Francois Triozon +5
We report fully quantum simulations of realistic models of boron-doped graphene-based field effect transistors, including atomistic details based on DFT calculations. We show that…
