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.

拟议的联合项目旨在启动国际领先的碳纳米管（CN）量子输运研究计划。在两个小组（埃克塞特实验组和伯明翰理论组）的共同努力下，我们希望对受控无序对 CNs 电性能的影响进行系统研究。对这些独特的一维物体的研究正在迅速扩大，尽管它们在英国的代表性仍然不足。现有的研究集中在干净或肮脏的系统上。我们将研究金属系统如何根据无序性转变为强相关绝缘态或安德森绝缘体。将采用一系列免费的实验技术。这些实验将得到无序情况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（例如量子开关）的新原理。
