Aharonov-Bohm spectral features and coherence lengths in carbon nanotubes
S. Roche, G. Dresselhaus, M. S. Dresselhaus +1
The electronic properties of carbon nanotubes are investigated in the presence of disorder and a magnetic field parallel or perpendicular to the nanotube axis. In the parallel fiel…
Effects of magnetic field and disorder on electronic properties of Carbon Nanotubes
Stephan Roche, Riichiro Saito
Electronic properties of metallic and semiconducting carbon nanotubes are investigated in presence of magnetic field perpendicular to the CN-axis, and disorder introduced through e…
Fermi surfaces and anomalous transport in quasicrystals
S. Roche, T. Fujiwara
Fermi surfaces of several quasicrystalline approximants are calculated by means of ab-initio methods which enable direct comparison with dHvA experiments. A criterion for anomalous…
Investigation of quantum transport by means of O(N) real-space methods
S. Roche
Quantum transport for different systems is investigated by developing the Kubo formula on a basis of orthogonal polynomials. Results on quantum Hall systems are presented with part…
Electronic transport properties of quasicrystals: a Review
S. Roche, Guy Trambly de Laissardiere, D. Mayou
We present a review of some results concerning electronic transport properties of quasicrystals. After a short introduction to the basic concepts of quasiperiodicity, we consider t…
