Transport through a double quantum dot system with non-collinearly polarized leads
Ralph Peter Hornberger, Sonja Koller, Georg Begemann +2
We investigate linear and non-linear transport in a double quantum dot system weakly coupled to spin-polarized leads. In the linear regime, the conductance as well as the non-equil…
The low energy spectrum of finite size metallic SWNTs
Leonhard Mayrhofer, Milena Grifoni
The electronic spectrum of metallic finite-size single-wall carbon nanotubes at low energies is derived. It is based on a tight-binding description for the interacting p_{z} electr…
Bloch's theory in periodic structures with Rashba's spin-orbit interaction
S. Smirnov, D. Bercioux, M. Grifoni
We consider a two-dimensional electron gas with Rashba's spin-orbit interaction and two in-plane potentials superimposed along directions perpendicular to each other. The first of…
Spin transport across carbon nanotube quantum dots
Sonja Koller, Leonhard Mayrhofer, Milena Grifoni
We investigate linear and nonlinear transport in interacting single wall carbon nanotubes (SWCNTs) that are weakly attached to ferromagnetic leads. For the reduced density matrix o…
Schottky-barrier double-walled carbon nanotube field-effect transistors
Shidong Wang, Milena Grifoni
We investigate electronic transport properties of Schottky-barrier field-effect transistors (FET) based on double-walled carbon nanotubes (DWNT) with a semiconducting outer shell a…
