This book was released on 2017-10-26 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on the nanomanufacturing of graphene—a newly discovered, two-dimensional material with extraordinary properties—in order to realize its numerous potential applications. Combining experimental implementation with theoretical modelling, it investigates three classes of graphene nanostructure fabrication using particle beam irradiation: (i) doping of graphene using low energy nitrogen irradiation; (ii) joining of graphene sheets with laser and C, N, and Ar ion beam irradiation; and (iii) fabrication of graphene nanopores by means of focused ion beam and electron beam irradiation. The feasibility of the nanomanufacture of graphene using particle beam irradiation is demonstrated by various experimental methods, and the mechanisms involved under different types of beam irradiation are revealed using theoretical calculations. Further, the book analyzes the mechanical and electrical properties of the fabricated graphene nanostructures by means of atomic simulations to predict the application potentials of the proposed methods. The findings help promote the implementation of graphene-structure applications in industry.

Download or read book Effect of Laser Irradiation of Structural and Electrical Properties of CVD Grown Graphene written by Michelle Nicole Langhoff and published by . This book was released on 2013 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Graphene is the first discovered 2-D material. Its structure is composed of a honeycomb shaped lattice composed of sp2 bonded carbon atoms. Its structural properties can be studied in great detail using Raman spectroscopy. However, of great interest are its electrical properties. Theoretically, graphene's charge carriers can be tuned continuously to values as high as 10113 cm-2 and its mobility can be as high as on the order of 120,000 cm2/(V*s). While this entices researchers, there are difficulties due to graphene's linear IV curve and the lack of control over its doping levels. This research seeks to use laser irradiation to modify graphene's properties. In the first instance, laser irradiation can be used to remove excess residue, thereby allowing graphene to better achieve its mobility potential. Nonetheless, one must remain cognizant that this process may cause differences in graphene's structural properties that may alter its electrical characteristics. Using field effect transistor measurements and Hall Effect measurements, this research addresses these alterations. It was found that laser irradiation in vacuum causes increased carrier concentration and decreased mobility. Alternatively, annealing the sample in forming gas causes decreased carrier concentration and increased mobility. Hence, it is seen that the doping level of the graphene can be modified using laser irradiation and annealing in different environments.

Download or read book Effects of Neutron and Gamma Radiation on Carbon Nanotubes and Three dimensional Graphene Sheets written by Rukmini Gorthy and published by . This book was released on 2016 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research paper explores the possibility that treating nanomaterials with radiation from neutrons or photons will simulate the processes of diffusion and mass transfer, recovery and recrystallization, formation and interaction of defects. The defects in irradiated CNTs are mostly restricted to the outer layers. Although they appear to be well separated at the beginning, the increase in dosage may cause them to melt and eventually thicken. The most common structural defects one can notice in CNTs are atomic vacancies, topological defects, dangling bonds, microvoids and Stone-Wales defects. When graphene is irradiated there is a possibility that the high-energy particles induce morphological changes. Increase in dosage of radiation is inversely proportional to the probability of production of complex defects. Graphene has a unique property of hosting lattice defects in reconstructed atom arrangements. These defects locally increase the reactivity of the structure and allow adsorption of other atoms on graphene. The most common structural defects in graphene are Stone-Wales defects, single vacancies, reconstructed double vacancies, adatoms or interstitial atoms, substitutional impurities and line defects or one dimensional defects. Raman Spectroscopy and Thermo-Gravimetric Analysis were used in characterizing the materials and Transmission Electron microscope to image the materials before and after exposure to irradiation. To further study how the irradiation modified the nanomaterials some of them were dispersed in water. The pristine samples do not disperse due to the lack of defects while the ones exposed to radiation show that they form a homogenous mixture in some cases.
