Nanotubes are the giant molecules which can be produced from the sheets of carbon atoms coaxially arranged in a cylindrical shape. In this talk we present a review of CNTs (carbon nanotubes) properties and applications [1]. We start from a description of their geometry, p-electron band structure, as well as electrical conductivity of individual (single) carbon nanotubes. It is pointed out that they can possess metal, semiconducting, and superconducting properties. The large spin-orbit interactions determined by ideal cylindrical structure of nanotubes can be explained. The operations of nanodevices based on the single CNT-like diodes, single-electron and field-effect transistors, memory devices as well as chemical sensors are discussed. Special attention is paid to the nanotube field-emission and electromechanical devices. Reference
