Spin-valley blockade in carbon nanotube double quantum dots
We present a theoretical study of the Pauli or spin-valley blockade for double quantum dots in semiconducting carbon nanotubes. In our model, we take into account the following characteristic features of carbon nanotubes: i fourfold spin and valley degeneracy of the quantum-dot levels, ii the intrinsic spin-orbit interaction which is enhanced by the tube curvature, and iii valley mixing due to ...
متن کاملSpin transport across carbon nanotube quantum dots
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 of a SWCNT quantum dot, equations of motion which account for an arbitrarily vectored magnetisation of the contacts are derived. We focus on the case of large diameter nanotubes where exchange effects emerging from sho...

متن کاملElectrically induced ambipolar spin vanishments in carbon nanotubes
Carbon nanotubes (CNTs) exhibit various excellent properties, such as ballistic transport. However, their electrically induced charge carriers and the relation between their spin states and the ballistic transport have not yet been microscopically investigated because of experimental difficulties. Here we show an electron spin resonance (ESR) study of semiconducting single-walled CNT thin films...
متن کاملElectrically tunable spin polarization in a carbon nanotube spin diode.
We have studied the current through a carbon-nanotube quantum dot with one ferromagnetic and one normal-metal lead. For the values of gate voltage at which the normal lead is resonant with the single available nondegenerate energy level on the dot, we observe a pronounced decrease in the current for one bias direction. We show that this rectification is spin dependent, and that it stems from th...
