Summary on Grant Application Form |
|
The proposed research will provide a comprehensive understanding of geometry-induced transport in multi-wall and multiply-connected NTs and wi underpin possible molecular-electronic device developments using NTs. The effect of contacting NTs to superconductors and ferromagnets will be studied in detail. Experiments on NT-based Andreev interferometers are currently being planned at Basel and the LTL Finland. The proposed theon work will predict the effect of twists, bends and chirality on the conductance-phase relations of such structures. In view of recent experiments suggesting superconductivity in NTs may be stabilised by contact to superconducting reservoirs, we shall compute the critical current of NT-based Josephson junctions as a function of chirality and geometric distortions, in both single and mufti-wall NTs. We shall also investigate spin-polarized transport in NT-based spin valves, with a view to examining the effect of chirality and distortions on giant magneto-resistance. The aim will be to understand how to optimise the GMR ratio in ferromagnetic-NT nanostructures. The torque on the magnetic moment of a ferromagnetic island indu by a spin-polarized current will also be computed, with a view to investigating the possibility of current-induced switching.
