ABSTRACT
This chapter presents a description of key solid-state concepts required to understand nanotransistors. Carbon materials can be seen in many structural forms such as fullerenes, graphite, carbon fibers, carbon nanotubes (CNTs), and diamond. The chapter presents and discusses that the electrical structure of CNT was the first to attract the attention of scientists, several other outstanding properties of the structure made these nanomaterials very remarkable candidates for several interesting applications. It also presents the discovery of CNT and its methods of fabrication as well as depicts the properties of these unique nanomaterials. The chapter explains the experimental observations and the subseqnent theoretical studies over the discovered unique nanostructures led to the finding of many amazing properties and applications for the structure. It presents a historical review of CNT and silicon nanowire (SNW) research and basic definitions related to their structural properties. The chapter discusses the applications of CNT and SNW in electronics.
