This book was released on 2013-03-14 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, molecular electronics, especially that utilizing single molecules, has been attracting much attention. This is mainly because the theoretical limit is approaching in the present silicon-based technology, and the development of an alternative process is strongly desired. Single-molecule electronics is aimed at a breakthrough toward the next generation of computing systems. By designing and synthesizing highly functionalized molecules of nanometer size and incorporating these molecules into electrical circuits, we shall obtain much dense and high-speed processors. The concept of single-molecule electronics was first introduced by Aviram and Ratnar in 1978. In the early 1980s, many groups all over the world had started research on molecular electronics. At that time, single-molecule manipulation techniques had not been born, and the research was mainly carried out on molecular films formed by the Langmuir~Blodgett technique, a wet process, and by molecular-beam epitaxy, a dry process. A number of prototypes of switching devices and logic gates were, however, reported in the 1980s. In the early 1990s, scanning probe microscopes became popular and researchers obtained a single-molecule manipulation and evaluation tech nique. It became possible to fabricate practical devices using single molecules or small numbers of molecules. Finally, at the end of the last century, an explosion in the research field of single-molecule electronics was witnessed. In addition, studies of "biocomputing" started in the early 1980s and significant progress was achieved in the last century.

Book excerpt: Comprehensive Inorganic Chemistry II, Nine Volume Set reviews and examines topics of relevance to today’s inorganic chemists. Covering more interdisciplinary and high impact areas, Comprehensive Inorganic Chemistry II includes biological inorganic chemistry, solid state chemistry, materials chemistry, and nanoscience. The work is designed to follow on, with a different viewpoint and format, from our 1973 work, Comprehensive Inorganic Chemistry, edited by Bailar, Emeléus, Nyholm, and Trotman-Dickenson, which has received over 2,000 citations. The new work will also complement other recent Elsevier works in this area, Comprehensive Coordination Chemistry and Comprehensive Organometallic Chemistry, to form a trio of works covering the whole of modern inorganic chemistry. Chapters are designed to provide a valuable, long-standing scientific resource for both advanced students new to an area and researchers who need further background or answers to a particular problem on the elements, their compounds, or applications. Chapters are written by teams of leading experts, under the guidance of the Volume Editors and the Editors-in-Chief. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource for information in the field. The chapters will not provide basic data on the elements, which is available from many sources (and the original work), but instead concentrate on applications of the elements and their compounds. Provides a comprehensive review which serves to put many advances in perspective and allows the reader to make connections to related fields, such as: biological inorganic chemistry, materials chemistry, solid state chemistry and nanoscience Inorganic chemistry is rapidly developing, which brings about the need for a reference resource such as this that summarise recent developments and simultaneously provide background information Forms the new definitive source for researchers interested in elements and their applications; completely replacing the highly cited first edition, which published in 1973

Download or read book Atomic and Molecular Manipulation written by Andrew J. Mayne and published by Elsevier. This book was released on 2011-09-02 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Work with individual atoms and molecules aims to demonstrate that miniaturized electronic, optical, magnetic, and mechanical devices can operate ultimately even at the level of a single atom or molecule. As such, atomic and molecular manipulation has played an emblematic role in the development of the field of nanoscience. New methods based on the use of the scanning tunnelling microscope (STM) have been developed to characterize and manipulate all the degrees of freedom of individual atoms and molecules with an unprecedented precision. In the meantime, new concepts have emerged to design molecules and substrates having specific optical, mechanical and electronic functions, thus opening the way to the fabrication of real nano-machines. Manipulation of individual atoms and molecules has also opened up completely new areas of research and knowledge, raising fundamental questions of "Optics at the atomic scale", "Mechanics at the atomic scale", Electronics at the atomic scale", "Quantum physics at the atomic scale", and "Chemistry at the atomic scale". This book aims to illustrate the main aspects of this ongoing scientific adventure and to anticipate the major challenges for the future in "Atomic and molecular manipulation" from fundamental knowledge to the fabrication of atomic-scale devices. Provides a broad overview of the field to aid those new and entering into this research area Presents a review of the historical development and evolution of the field Offers a clear personalized view of current scanning probe microscopy research from world experts

Available in PDF, EPUB and Kindle. Book excerpt: This volume chronicles the proceedings of the Third Symposium on Metallized Plastics: Fundamental and Applied Aspects held under the auspices of the Dielectric Science and Technology Division of the Electrochemical Society in Phoenix, Arizona, October 13-18, 1991. This series of symposia to address the subject of metallized plastics was initiated in 1988 and the premier symposium was held in Chicago, October 10-12, 1988, followed by the second event in Montreal, Canada, May 7-10, 1990. The rroceedings of these two symposia have been properly documented ,2. The third symposium was a huge success like the previous two events, and all this is testimonial to the brisk interest and high tempo of R&D activity in the fie14 of metallized plastics. This further bolsters our earlier thinking that there was a conspicuous need to hold symposia on this topic on a regular basis and the fourth is planned for May 16-21, 1993 in Honolulu, Hawaii. The study of metallized plastics constitutes an important human endeavor l and as pointed out earlier there are myriad applications of metallized plastics ranging from very commonplace to exotic. Also a survey of the recent literature will reveal that both the fundamental and applied aspects of metallized plastics are being pursued with great vigor.

Download or read book The studies of thermal stability of molecular structures grown on oxide metal crystals by means of temperature programmed desorption TPD written by Karol Cieslik and published by Karol Cieslik. This book was released on with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic thin film devices’ performance depends on their properties, such as the crystallinity of the active layer and the specific arrangement of molecules in it. The morphology of molecular structures can be studied using imaging techniques (such as atomic force microscopy AFM, scanning tunneling microscopy STM, and scanning electron microscopy SEM),but to gain a more complete understanding of their nature, temperature programmed desorption (TPD) may be used. During a TPD experiment, the temperature of the adsorbate-adsorbent system is increased linearly while simultaneously the number of desorbing molecules is measured. The resulting TPD spectrum may be used to determine the type of structure (monolayer, multilayer) and the desorption energy associated with it. Furthermore, the thermal stability of observed structures, as determined by the temperatures at which desorption occurs, is evident from the TPD spectra. Thus, TPD measurements may lead to a better understanding of the growth and characteristics of molecular structures which may be of use for potential applications in organic electronics. The first aim of this thesis was the assembly and calibration of the TPD system. The optimal parameters of the mass spectrometer (ionizer’s emission current and electron energy) were determined. Moreover, the linear heating of the samples using direct resistive heating was established. The optimal mass-to-charge ratio for para-hexaphenyl (6P) was determined based on the mass spectrum of 6P. The final test of the TPD system was a comparison of the measured TPD spectrum of 6P film grown on mica(001) with the one published in the literature. The second aim was the measurement of spectra of 6P films on ion-beam modified (110) surfaces of TiO2. Two substrates of different topographies (determined by STM) were studied: one with deep ripples (height modulation of 2.6nm) and one with shallow ripples (height modulation of 0.76nm).In the case of the deep-rippled sample, the effect of molecular film coverage, and the desorption from the sample holder on the measured spectra was investigated. In contrast, the shallow-rippled sample was only studied in the context of the effect of desorption from the sample holder on the spectra. The morphology of 1.91nm thin film of 6P on the deep-rippled sample was studied using SEM, while the morphology of a 0.57nm thin 6P film on shallow-rippled TiO2(110) was determined using STM and AFM. Additionally, the desorption of 6P powder from an effusion cell was studied for comparison of the bulk and thin-film desorption parameters. The optimal parameters for the spectrometer’s ionizer were determined to be: emission current of 700μA, electron energy of 37eV, and use of two filaments. The chosen mass-to-charge ratio was 229.35, e.i. 6P with 2+ charge. The TPD spectrum of 1.91nm of 6P on mica(001) contained a multilayer peak at temperature 222℃ which was in agreement with published data. Due to desorption from the sample holder, all spectra in the TPD experiments showed additional peaks and an increase in background intensity. This effect was almost completely eliminated by covering parts of the holder with tantalum sheets during the molecule deposition process. The TPD spectra for 6P grown on both samples contained two peaks: one which began at approximately 180℃ and ended at different temperatures depending on coverage and another which began at 300℃(the complete spectrum for the deep-rippled sample was not measured, but the peak ended at 550℃ for the shallow-ripples sample). The first peak is due to multilayered molecular structures, which, based on morphologies of the samples, can be identified as originating from standing-molecule islands and laying-molecule nanoneedles in the case of deep-rippled, and laying-molecule nanoneedles for shallow-rippled TiO2(110). The second peak is probably due to a monolayer of 6P molecules laying directly on the TiO2 surface (such a layer was observed for the shallow-rippled sample).

Download or read book On Surface Synthesis II written by Dimas G. de Oteyza and published by Springer. This book was released on 2018-03-19 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: On-surface synthesis is appearing as an extremely promising strategy to create organic nanoarchitectures with atomic precision. Molecular building blocks holding adequate functional groups are dosed onto surfaces that support or even drive their covalent linkage. The surface confinement and the frequent lack of solvents (most commonly being performed under vacuum conditions) create a completely new scenario fully complementary to conventional chemistry. In a pedagogical way and based on the most recent developments, this volume presents our current understanding in the field, addressing fundamental reaction mechanisms, synthetic strategies to influence the reactions according to our needs, as well as the ultimate growth and characterization of functional materials. Verging on chemistry, physics and materials science, the book is aimed at students and researchers interested in nanochemistry, surface science, supramolecular materials and molecular devices. Chapters "Mechanistic insights into surface-supported chemical reactions", "Reactivity on and of Graphene Layers: Scanning Probe Microscopy Reviels" and "Bottom-up fabrication of atomically precise graphene nanoribbons" of this book are available open access under a CC BY 4.0 license at link.springer.com
