摘要：
The Rashba spin-orbit coupling in carbon nanotubes and its effect on spin-dependent transport properties are analysed theoretically. We focus on clean non-interacting nanotubes with tunable number of subbands N. The peculiar band structure is shown to allow in principle Datta-Das oscillatory behaviour in the tunnelling magnetoresistance as a function of gate voltage, despite the presence of multiple bands. We discuss the conditions for observing Datta-Das oscillations in carbon nanotubes.
