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(CNS)量子传输研究计划。在两个小组的共同努力下(埃克塞特的实验和伯明翰的理论)，我们希望对受控无序对中枢神经系统的电学性质的影响进行系统的研究。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很低。现有的研究集中在干净或肮脏的系统上。我们将研究依赖于无序，金属系统是如何转变为强关联绝缘态或安德森绝缘体的。将采用一系列免费的实验技术。这些实验将得到无序存在时一维量子传输理论的发展的支持。我们还将探索将CNS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.
