The magnetotransport and specifically the spintransport properties of B-, N-, BN- and P-doped single-walled and multi-walled carbon nanotubes is to be investigated.

This implies experimental work in nano-device fabrication (lithography) using individual tubes, structural characterisation (scanning-force and -electron microscopy), and electrical measurements in magnetic fields and within the temperature range from 300 K down to a few ten mK.

The transport effects primarily to be investigated in the doped tubes, which are expected to show due to the dopants enhanced magnetic-/spin-coupling of charge-carriers, are the spin-valve-effect, Coulomb-blockade, and Kondo-effect, in particular in view of varying the electrode material (ferromagnetic, non-ferromagnetic) used for the electrical contating of individual tubes (spin-injection process).
