S. Subramoney, in Encyclopedia of Materials: Science and Technology, 2006. Introduction. In the article Carbon Nanotubes, the synthesis, structure, properties, and potential applications of multiwalled and single-walled variants of carbon were discussed extensively.In continuation of the previous work, this article addresses the key issues on hand in carbon nanotube technology.
Thermal Properties and Nanoelectromechanical System Based on Carbon Nanotubes Thesis by Hsin-Ying Chiu In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy California Institute of Technology Pasadena, California 2009 (Defended February 17, 2009).
This thesis investigates the use of the Langmuir-Blodgett (LB) deposition technique as a means for building up ultra-thin networks of single-walled carbon nanotubes (SWCNTs) on various substrates. Transfer from a water subphase is successfully demonstrated for a range of SWCNTs and the electrical properties of the networks are discussed in detail.
Introduction. Alexey Tsapenko is among the first PhD graduates of Skoltech’s Center for Photonics and Quantum Materials. His thesis, “Enhancing Optoelectronic Performance of Randomly Oriented Single-Walled Carbon Nanotube Films”, focuses on carbon nanotubes, a field of technology that could be a benefit to many industrial sectors, particularly cars, aircraft, wearables, and touchscreen.
This thesis reports on the chemical vapour deposition (CVD) growth of carbon nanostructures (mainly carbon nanotubes (CNTs)) on perovskite oxide surfaces with the aid of various catalysts. Two types of perovskite oxide, single crystal SrTiO3 (001) and polycrystalline BaSrTiO3, have been used as.
This thesis addresses two routes towards this goal. The detection of charge transport through quantum dots using a GaAs point contact is a potential tool for quantum computation. This project aimed to fabricate and measure hybrid devices with carbon nanotube quantum dots on top of GaAs point contacts. Dispersion and AFM manipulations of.
This thesis presents research into spin-transport in Carbon nanotube quantum dots. Sputtered Permalloy electrodes designed with shape anisotropy were used to contact Carbon nanotubes grown by chemicalvapour deposition in lateral spin-valve structures. The magnetoresistance of these spin-valves were measured at low-temperatures and as a function of the charge state of the quantum dots.

PhD thesis, Concordia University. Graphene and carbon nanotubes are ideal for strain engineering in quantum nanoelectromechanical systems due to their long coherence lengths, mechanical strength, and sensitivity to deformations. Thus far, experimental carbon have prevented thorough exploration of quantum transport strain engineering QTSE. We.
The theoretical minimum diameter of a carbon nanotube is around 0.4 nanometers, which is about as long as two silicon atoms side by side, and nanotubes this size have been made. Average diameters tend to be around the 1.2 nanometer mark, depending on the process used to create them. 8 SWNTs are more pliable than their multi-walled counterparts and can be twisted, flattened and bent into small.
In conclusion, the relevant factors limiting the performance of mechanical dry-transfer based carbon nanotube transistors were identified and post processing techniques to overcome these issues were suggested and, as far as possible within the scope of this thesis, demonstrated.
Structure of single-walled tubes. The structure of an ideal (infinitely long) single-walled carbon nanotube is that of a regular hexagonal lattice drawn on an infinite cylindrical surface, whose vertices are the positions of the carbon atoms. Since the length of the carbon-carbon bonds is fairly fixed, there are constraints on the diameter of the cylinder and the arrangement of the atoms on it.
