Quantum transport in carbon nanotubes
In the last twenty years, due to technological advances, it has become possible to build, manipulate and observe nanometer structures and so their dimensions are intermediate between the microscopic and macroscopic. These new systems present novel features and have originated the new field of mesoscopic physics As for the transport properties the mesoscopic conductors do not have ohmic behaviou...
متن کاملQuantum-dot transport in carbon nanotubes
Transport measurements on a bundle of single-walled carbon nanotubes have been made below 4.2 K as a function of side gate and source–drain bias voltage. The transport of an individual nanotube is described by the Coulomb blockade effect. The zero-dimensional quantum states of the nanotube become clear for measurements of large bias voltage. In addition, we present preliminary results of microw...
متن کاملQuantum dots in carbon nanotubes
In this overview paper, we present low-temperature electronic transport measurements of carbon nanotube quantum dots with a back gate. In a semiconducting tube, charge carriers could be completely depleted. The addition energy and the excitation spectrum have been studied as a function of the number of charges (electrons or holes), one by one. We observe electron–hole symmetry, which is a direc...
متن کاملQuantum entanglement in carbon nanotubes.
With the surge of research in quantum information, the issue of producing entangled states has gained prominence. Here, we show that judiciously bringing together two systems of strongly interacting electrons with vastly differing ground states-the gapped BCS superconductor and the Luttinger liquid-can result in quantum entanglement. We propose three sets of measurements involving single-walled...
متن کاملSingle-wall Carbon Nanotubes: Quantum Carbon Wires
Today’s business environment is causing utilities to examine methods to cut costs and to maximize revenues. Development of a comprehensive program for marketing and utilization* of coal combustion by-products (CCBPs) by a utility can generate additional revenue streams; reduce operating costs at plants; and defer capital costs of developing new waste disposal capacity. These factors can be opti...
