Electronic structure and transport in approximants of the Penrose tiling
Guy Trambly de Laissardière, Attila Szállás, Didier Mayou
We present numerical calculations of electronic structure and transport in Penrose approximants. The electronic structure of perfect approximants shows a spiky density of states an…
Conductivity of Graphene with Resonant Adsorbates: Beyond the Nearest Neighbor Hopping Model
Guy Trambly de Laissardière, Didier Mayou
Adsorbates on graphene can create resonances that lead to efficient electron scattering and strongly affect the electronic conductivity. Therefore a proper description of these res…
Anomalous electronic transport in Quasicrystals and related Complex Metallic Alloys
Guy Trambly de Laissardière, Didier Mayou
We analyze the transport properties in approximants of quasicrystals alpha-AlMnSi, 1/1-AlCuFe and for the complex metallic phase lambda-AlMn. These phases presents strong analogies…
Fano Interference between a STM Tip and Mid Gap States in Graphene
Omid Faizy Namarvar, Didier Mayou
We analyze the STM current through electronic resonances on a substrate as a function of tip-surface distance. We show that when the tip approaches the surface a Fano hybridization…
