Spin Effects in Quantum Transport in Carbon Nanotubes

本项目主要研究含缺陷碳纳米管(CNTs)量子输运中的自旋效应。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：双端设置-CNT连接到源极和漏极触点-以及三端设置-扫描隧道显微镜(STM)的尖端被添加到两端设置中。后栅改变碳纳米管的电化学势的影响将被包括在内。还将讨论由碳纳米管中的铁磁接触和自旋-轨道相互作用(SOI)引起的自旋效应。

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.
