Download or read book Surface Enhanced Raman Spectrometry of C60 in an Electron Tunneling Gap written by Erin E. Perry (S.B.) and published by . This book was released on 2013 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanogap devices have applications in single molecule sensing and single molecule transistors. Nanogap devices comprised of a gold nanowire with a nanoscale gap containing C60 were fabricated using electromigration on a silicon substrate. Raman spectra were obtained for various features of this device in order to detect the presence of C6o and study its electronic properties. The 532 nm laser source showed Raman peaks at 300,522,930-980, 1570, 1900 and 2150 cm-1 and the 632 nm laser source showed Raman peaks at 300, 522, 930-980, 1460, and 2124 cm-1. The device feature (gold, C60, silicon or combination thereof) responsible these peaks' presence in Raman spectra was determined. There was peak broadening present at long wavelengths for gold features in the Raman spectra taken using the 532 nm laser and for spectra using the 632 nm laser when C60 is present in high concentrations. This is believed to be an effect of the creation of defects in the C60 lattice due to the presence of oxygen, resulting in Frenkel excitons becoming trapped. When the Frenkel excitons recombine, they emit light causing the photoluminescence at longer wavelengths. Peak broadening was also studied in devices comprised of a gold nanoparticle substrate with C60 spun cast onto the surface. Raman spectra of nanoparticle and nanogap devices shared similar features.
Download or read book Surface Enhanced Raman Spectroscopy of Electroactive Films of C60 and an Ir C60 Complex on Gold Symmetry Lowering Electron Localization and Counteraction Effects written by and published by . This book was released on 1993 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface-enhanced Raman (SER) spectra are reported for thin films of C60 and (eta 5-C9H7)Ir(CO)(eta2-C60) on gold electrodes in acetonitrile. The latter spectra display the hallmarks of vibrational symmetry lowering for C60 arising from metal coordination, involving splitting of the normally degenerate H (sub g) modes and the appearance of vibrationally forbidden bands. Only a milder selection rule relaxation is observed for SERS of uncoordinated C60. Electroreduction of both C60 and the Ir-C60 complex yielded similar frequency downshifts in the Ag pentagonal pinch mode, indicating that electron addition to the latter is fullerene localized. These spectral shifts are sensitive to the nature of the countercation.

Download or read book Fullerene Research 1985 1993 written by Tibor Braun and published by World Scientific. This book was released on 1995 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains very carefully compiled material presenting bibliographic descriptions of approximately 3500 papers, with a computer-generated index on authors, subject headings, corporate addresses and journals. There are many on-line services available on fullerenes, but they serve mainly current-awareness functions; none of them is selectively complete and carefully indexed and none can replace a complete retrospective bibliography, which most researchers in the field would want to have on hand in their laboratories and offices.

Book excerpt: This book presents the latest results of quantum properties of light in the nanostructured environment supporting surface plasmons, including waveguide quantum electrodynamics, quantum emitters, strong-coupling phenomena and lasing in plasmonic structures. Different approaches are described for controlling the emission and propagation of light with extreme light confinement and field enhancement provided by surface plasmons. Recent progress is reviewed in both experimental and theoretical investigations within quantum plasmonics, elucidating the fundamental physical phenomena involved and discussing the realization of quantum-controlled devices, including single-photon sources, transistors and ultra-compact circuitry at the nanoscale.
Download or read book Comprehensive Semiconductor Science and Technology written by and published by Newnes. This book was released on 2011-01-28 with total page 3572 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semiconductors are at the heart of modern living. Almost everything we do, be it work, travel, communication, or entertainment, all depend on some feature of semiconductor technology. Comprehensive Semiconductor Science and Technology, Six Volume Set captures the breadth of this important field, and presents it in a single source to the large audience who study, make, and exploit semiconductors. Previous attempts at this achievement have been abbreviated, and have omitted important topics. Written and Edited by a truly international team of experts, this work delivers an objective yet cohesive global review of the semiconductor world. The work is divided into three sections. The first section is concerned with the fundamental physics of semiconductors, showing how the electronic features and the lattice dynamics change drastically when systems vary from bulk to a low-dimensional structure and further to a nanometer size. Throughout this section there is an emphasis on the full understanding of the underlying physics. The second section deals largely with the transformation of the conceptual framework of solid state physics into devices and systems which require the growth of extremely high purity, nearly defect-free bulk and epitaxial materials. The last section is devoted to exploitation of the knowledge described in the previous sections to highlight the spectrum of devices we see all around us. Provides a comprehensive global picture of the semiconductor world Each of the work's three sections presents a complete description of one aspect of the whole Written and Edited by a truly international team of experts

Available in PDF, EPUB and Kindle. Book excerpt: In the last few years, Nanoparticles and their applications dramatically diverted science in the direction of brand new philosophy. The properties of many conventional materials changed when formed from nanoparticles. Nanoparticles have a greater surface area per weight than larger particles which causes them to be more reactive and effective than other molecules. In this book, we (InTech publisher, editor and authors) have invested a lot of effort to include 25 most advanced technology chapters. The book is organised into three well-heeled parts. We would like to invite all Nanotechnology scientists to read and share the knowledge and contents of this book.
