Available in PDF, EPUB and Kindle. Book excerpt: The intense interest in graphene as the prototype 2D electronic material has recently been complemented by the investigation of layered transition metal dichalcogenides (TMD), notably MoS2 and MoSe2 . These materials provide the favorable mechanical properties of graphene, but exhibit a direct bandgap without the need for nanostructuring, chemical functionalization, or the application of a strong electric field to bilayers. As a monolayer, MoS2 becomes a direct-gap semiconductor with a gap of 1.8 eV. In this dissertation, X-ray photoelectron spectroscopy (XPS), photoluminescence, spectroscopy and high-resolution angle resolved photoemission spectroscopy (ARPES) have been used to investigate monolayer and alloy thin films grown on various substrates. My research focuses on the thin film modification and characterization, composition analysis, low-energy argon ion sputtering process and bandgap tuning.
Download or read book Crystallization of Two dimensional Transition Metal Dichalcogenides for Tailored Optical Properties written by Rachel H. Rai and published by . This book was released on 2019 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two dimensional (2D) semiconducting transition metal dichalcogenides (TMD) are new materials that exhibit unique and useful combinations of physical properties, such as photoluminescence (PL) in the visible to NIR frequencies coupled with mechanical flexibility. Such properties make 2D TMDs attractive candidates for the next generation of compact, unobtrusive, and low-cost opto-electronic technologies. However, the incorporation of 2D TMDs in commercial applications and products is currently limited by the absence of synthesis approaches yielding uniform, large area films with desired properties. Thus, this work encompasses innovative techniques to tailor optical properties of TMD thin films by controlling their area, thickness, grain size, defect density and uniformity during and after processing. These new approaches start with magnetron sputtering of ultra-thin amorphous TMD films on either flexible or rigid substrates. The amorphous precursor films were then subjected to illumination with energy beams to induce crystallization, including laser light, broadband radiation from a xenon lamp, and nanoscale electron beams. Magnetron sputtering was selected as the precursor deposition technique due to the large area capability coupled with low processing temperatures, allowing deposition directly on polymer substrates. Furthermore, modulation of the energy flux to the growing film during magnetron sputtering (by controlling the flux of incident energetic particles) provided an opportunity to control the density of pre-existing nuclei in the amorphous material for an added measure of structural control upon illumination. The structure, composition and optical properties of crystalline 2D TMD materials on flexible and rigid substrates after illumination, were then correlated to the pre-existing amorphous structure and process conditions for selected TMD compositions. Important conclusions from the work include significant insight on the mechanisms of crystallization kinetics, as well as new correlations of structure to optical properties, including a dependence on photoluminescence intensity accompanied by a change in crystal edge density, correlating well to theory. In summary, this work employs various crystallization techniques to understand nucleation and growth of 2D TMD materials, and application of nucleation and growth mechanisms to control optical properties.

Download or read book Handbook of Carbon Graphite Diamonds and Fullerenes written by Hugh O. Pierson and published by William Andrew. This book was released on 2012-12-02 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a review of the science and technology of the element carbon and its allotropes: graphite, diamond and the fullerenes. This field has expanded greatly in the last three decades stimulated by many major discoveries such as carbon fibers, low-pressure diamond, and the fullerenes. The need for such a book has been felt for some time. These carbon materials are very different in structure and properties. Some are very old (charcoal), others brand new (the fullerenes). They have different applications and markets and are produced by different segments of the industry.Few studies are available that attempt to review the entire field of carbon as a whole discipline. Moreover these studies were written several decades ago and a generally outdated since the development of the technology is moving very rapidly and scope of applications is constantly expanding and reaching into new fields such as aerospace, automotive, semiconductors, optics, and electronics. In this book the author provides a valuable, up-to-date account of both the newer and traditional forms of carbon, both naturally occurring and man-made. This volume will be a valuable resource for both specialists in, and occasional users of carbon materials.

Download or read book Polymer Electrolyte Fuel Cell Durability written by Felix N. Büchi and published by Springer Science & Business Media. This book was released on 2009-02-08 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers a significant number of R&D projects, performed mostly after 2000, devoted to the understanding and prevention of performance degradation processes in polymer electrolyte fuel cells (PEFCs). The extent and severity of performance degradation processes in PEFCs were recognized rather gradually. Indeed, the recognition overlapped with a significant number of industrial dem- strations of fuel cell powered vehicles, which would suggest a degree of technology maturity beyond the resaolution of fundamental failure mechanisms. An intriguing question, therefore, is why has there been this apparent delay in addressing fun- mental performance stability requirements. The apparent answer is that testing of the power system under fully realistic operation conditions was one prerequisite for revealing the nature and extent of some key modes of PEFC stack failure. Such modes of failure were not exposed to a similar degree, or not at all, in earlier tests of PEFC stacks which were not performed under fully relevant conditions, parti- larly such tests which did not include multiple on–off and/or high power–low power cycles typical for transportation and mobile power applications of PEFCs. Long-term testing of PEFCs reported in the early 1990s by both Los Alamos National Laboratory and Ballard Power was performed under conditions of c- stant cell voltage, typically near the maximum power point of the PEFC.
