Available in PDF, EPUB and Kindle. Book excerpt: Carbon nanotubes (CNTs) are tubular cylinders of carbon atoms that have extraordinary mechanical, electrical, thermal, optical and chemical properties. CNTs typically have diameters ranging from 1 nanometer (nm) up to 50 nma nanometer is one thousand millionth of a meter. Typical CNT lengths are several micronsseveral thousand nanometers long; by contrast, Nanocomp's produced fibers are measured in millimetersthousands of times longer than all other commercially produced CNTs. They take the form of cylindrical carbon molecules and have novel properties that make them potentially useful in a wide variety of applications in nanotechnology, electronics, optics and other fields of materials science. They exhibit extraordinary strength and unique electrical properties, and are efficient conductors of heat. In the powdery format offered by all CNT producers (but for NTI), applications are limited to the properties possible by this form factore.g. additive active ingredients in semiconductors, liquid crystal displays (LCDs), sensors, and other uses in which these powders add some level of functional performance. Due to its fiber length and its form factors, NTI delivers strength and conductivity unlike any other commercial CNT producer, and so can address a much broader array of applications for which its material rivals copper and aluminum in conductivity, and steel, aluminum, carbon fibers and glass composites where strength and lightweight matter. Carbon nanotubes have been a subject of exhaustive research for a wide range of applications. The purpose of this book entitled Properties of Carbon Nanotubes is to give in-depth understanding of the physics and electronic structure of carbon nanotubes. This book discusses fabrication techniques followed by an analysis on the physical properties of carbon nanotubes, including density of states and electronic structures. Eventually, the book follows a significant amount of work in the industry applications of carbon nanotubes.

Download or read book Doping of Carbon Nanotubes written by Sergey Bulyarskiy and published by Springer. This book was released on 2017-07-01 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the control of electronic properties of carbon nanotubes. It presents thermodynamic calculations of the formation of impurities and defects in the interaction of nanotubes with hydrogen, oxygen, nitrogen and boron, based on theoretical models of the formation of defects in carbon nanotubes. It is shown that doping and adsorption lead to changes in the electronic structure of the tubes as well as to the appearance of impurity states in the HOMO-LUMO gap. The book presents examples of specific calculations for doping of carbon nanotubes with oxygen, hydrogen, nitrogen and boron, together with numerous experimental results and a comparison with the author’s thermodynamic calculations. Possible directions of the technological processes of optimization are pointed out, as well as the perspectives of p-n-transition creation with the help of carbon nanotube arrays. The results presented were derived from the physics of the processes and a theoretical model of the technological processes. Though a wealth of empirical information on doping nanotubes has been accumulated in the scientific literature, what is lacking is a theoretical model for their analysis. As such, the book develops a thermodynamic model of the self-organization of structural elements in multicomponent systems – including carbon nanotubes, clusters and precipitates in condensed matter – and subsequently adapts it to the doping of carbon nanotubes. This approach allows readers to gain a far deeper understanding of the processes of doping carbon nanotubes.

Abstract: Carbon nanotubes (CNTs) are one-dimensional nanomaterials with interesting electronic properties and have potential applications in miniaturization of optoelectronic devices. Although various dispersants have been designed to functionalize CNTs, the optoelectronic properties of individual functionalized CNTs are yet to be fully explored. In this work, electrostatic force microscopy (EFM) and photoconductive atomic force microscopy (PCAFM) were utilized to characterize individual functionalized CNTs and rigorous statistical methodology for data analysis was applied to draw tenable conclusions. A poly(alkylthiophene)-based conjugated polyelectrolyte was used as a photosensitizer and a dispersant of CNTs to form a composite. EFM was performed for individual pristine CNTs and individual functionalized CNTs for comparison. It was the first time that charges of a polyelectrolyte on individual CNTs were quantitatively detected by EFM. PCAFM has revealed that the dominant charge transport mechanism of individual functionalized CNTs is Simmons tunneling. The large statistical dispersion of the PCAFM data necessitated rigorous statistical analysis to distinguish real effects of illumination from artifacts. The nonparametric bias-corrected and accelerated bootstrap method quantified the photoresponses conveniently without any presumption of the data distributions. The equilibrium conductance of an individual functionalized CNT exhibited a one-fold increase upon white light illumination. A series of ruthenium-containing diblock copolymers were synthesized by reversible addition-fragmentation chain transfer polymerization. The pyrene-containing first block acted as an anchoring group to interact with CNTs and the ruthenium(II) complexes in the second block acted as photosensitizers. Moieties with different electronic properties were conjugated to pyrene to tune the energy levels. The photoresponses of composites formed by these polymers were compared by PCAFM. The multiway factorial analysis of variance was employed to analyze the PCAFM data to investigate the effects of the dispersants, illumination condition and applied bias on the charge transport of the composites. The difference in photoresponse among different composites was related to the conformations of the composites, which were elucidated by molecular dynamics simulations, and the electronic properties of polymers, which were deduced by cyclic voltammetry and density functional theory calculations. The analysis suggests that the photogenerated charges from the metal complexes in the second block pass through the first block before reaching the CNT. The photoresponses of the CNT composites have potential applications in optoelectronic devices. With EFM to identify charged coatings and PCAFM to probe the photoresponses, individual functionalized CNTs can be characterized in detail. The rigorous statistical methodology can unravel the charge transport mechanism, which may provide guidelines for designing molecular devices. DOI: 10.5353/th_b5481867 Subjects: Carbon nanotubes
Download or read book The Science and Technology of Carbon Nanotubes written by T. Yamabe and published by Elsevier. This book was released on 1999-08-17 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon Nanotubes (CNT) is the material lying between fullerenes and graphite as a new member of carbon allotropes. The study of CNT has gradually become more and more independent from that of fullerenes. As a novel carbon material, CNTs will be far more useful and important than fullerenes from a practical point of view, in that they will be directly related to an ample field of nanotechnology. This book presents a timely, second-generation monograph covering as far as practical, application of CNT as the newest science of these materials. Most updated summaries for preparation, purification and structural characterisation of single walled CNT and multi walled CNT are given. Similarly, the most recent developments in the theoretical treatments of electronic structures and vibrational structures are covered. The newest magnetic, optical and electrical solid-state properties providing a vital base to actual application technologies are described. Explosive research trends towards application of CNTs, including the prospect for large-scale synthesis, are also introduced. It is the most remarkable feature of this monograph that it devotes more than a half of the whole volume to practical aspects and offers readers the newest developments of the science and technological aspects of CNTs.

This book was released on 2010 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract The functionalization of carbon nanotubes is a research topic with applications in a wide range of fields, from carbon nanotube based electronic sensor development to improving the electrical properties of carbon nanotubes for use as interconnects between larger circuit elements. This dissertation examines the impact of point-functionalizations on the conductance of single carbon nanotube devices. Due to their reduced size and dimensionality, carbon nanotubes act as an ideal system to electronically probe the characteristics of single functionalizations. Point-functionalizations can easily be introduced into carbon nanotube sidewalls using an electrochemical technique, which allows the experimenter to have total control over the rate of functionalization. The presence of point-functionalizations dominates the electronic properties of carbon nanotube devices. In this work, these sites are shown to be more chemically reactive, allowing metal nanoparticles to be selectively nucleated and grown on functionalized sites. Additionally, the presence of a single functionalized site coupled to a single palladium nanoparticle can be used to make a single carbon nanotube hydrogen sensor, with sensitivity down to the part per million level. Finally, cyclic voltammetry experiments show that point-functionalizations have much faster electron transfer rates than pristine carbon nanotubes alone.
