This project focusses on spin effects in quantum transport through carbon nanotubes (CNTs) with defects. The main goal of the project is the evaluation of the average charge and spin currents and of their fluctuations for two different configurations: a two-terminal setup-the CNT is connected to source and drain contacts – and a three-terminal setup – a tip of a scanning tunneling microscope (STM) is added to the two-terminal setup. The effect of a back gate varying the electrochemical potential of the CNT will be included. Spin effects induced by ferromagnetic contacts and by spin-orbit interactions (SOIs) in the CNTs will also be addressed.

这个项目的重点是通过缺陷的碳纳米管（CNT）的量子输运的自旋效应。该项目的主要目标是评估两种不同配置的平均电荷和自旋电流及其波动：两端设置-CNT连接到源极和漏极接触-和三端设置-扫描隧道显微镜（STM）的尖端添加到两端设置。将包括改变CNT的电化学电势的背栅的效果。还将讨论由铁磁接触和碳纳米管中的自旋轨道相互作用（SOI）引起的自旋效应。
