Disorder Controlled Quantum Transport in Carbon Nanotubes

拟议的联合项目旨在启动一个国际领先的碳纳米管量子传输研究方案。在两个小组（实验在埃克塞特和理论在伯明翰）的共同努力下，我们希望进行系统的研究控制无序的电性能的CN的影响。对这些独特的一维物体的研究正在迅速扩大，尽管它们在英国仍然代表性不足。现有的研究集中在清洁或肮脏的系统。我们将研究如何依赖于无序，金属系统被转移到一个强关联的绝缘状态或安德森绝缘体。将采用一系列补充实验技术。实验将得到无序条件下一维量子输运理论发展的支持。我们还将寻找将CN用于设备应用的新原理，例如量子开关。

The proposed joint project is aimed at launching an internationally leading programme of studies of quantum transport in carbon nanotubes (CNs). In a combined effort of two groups (experimental at Exeter and theoretical at Birmingham) we want to perform systematic research into the effects of controlled disorder on the electrical properties of CNs. Investigations of these unique one-dimensional objects are rapidly expanding, although they are still underrepresented in the UK. The existing studies concentrated on either clean or dirty systems. We will study how, dependent on disorder, the metallic system is transferred either into a strongly correlated insulating state or Anderson insulator. A range of complimentary experimental techniques will be employed. The experiments will be supported by the development of the theory of one-dimensional quantum transport in the presence of disorder. We will also search for new principles of using CNs for device applications, such as a quantum switch.
