This book was released on 2008 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many properties of the thin films are different from the bulk value and in many cases, depend dramatically on the film thickness. In the metallic ultra-thin films epitaxially grown on the semiconductor substrate, the conduction electrons are confined by the vacuum and metal-semiconductor interface. When the film thickness is comparable to the electron Fermi wavelength, this confinement will produce discrete energy levels known as quantum well states (QWS), which dramatically modify the electronic structures of the thin film and this is called quantum size effect (QSE). QSE will have a profound effect on a lot of physical properties of the thin films. Among various systems exhibiting QSE, Pb/Si (111) is the most widely studied one and exhibits the richest phenomena in QSE. In this study, a home made low temperature Scanning Tunneling Microscopy/Spectroscopy (LT-STM/S) was used to study the superconductivities of the Pb thin films. Quantum oscillations of the superconductivity have been observed for the films down to 4 monolayer and the oscillation amplitude increases as the film gets thinner. To resolve the discrepancies between the superconductivities measured with ex-situ transport and in-situ STS. We also studied the influence of Au overlay on the Pb thin films with LT-STM/S, and found out the deposition of Au on Pb dramatically roughened the Pb films. Finally, we successfully grew large scale near perfect 2ML Pb films. There are two types of films which exhibit different Moiré patterns. LT-STS studies revealed there is big difference in the superconductivity Tc of these two films, both of which decreased dramatically from that of the 4ML film.

Vilarinho and published by Springer Science & Business Media. This book was released on 2006-06-15 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the characteristic dimensions of electronic devices continue to shrink, the ability to characterize their electronic properties at the nanometer scale has come to be of outstanding importance. In this sense, Scanning Probe Microscopy (SPM) is becoming an indispensable tool, playing a key role in nanoscience and nanotechnology. SPM is opening new opportunities to measure semiconductor electronic properties with unprecedented spatial resolution. SPM is being successfully applied for nanoscale characterization of ferroelectric thin films. In the area of functional molecular materials it is being used as a probe to contact molecular structures in order to characterize their electrical properties, as a manipulator to assemble nanoparticles and nanotubes into simple devices, and as a tool to pattern molecular nanostructures. This book provides in-depth information on new and emerging applications of SPM to the field of materials science, namely in the areas of characterisation, device application and nanofabrication of functional materials. Starting with the general properties of functional materials the authors present an updated overview of the fundamentals of Scanning Probe Techniques and the application of SPM techniques to the characterization of specified functional materials such as piezoelectric and ferroelectric and to the fabrication of some nano electronic devices. Its uniqueness is in the combination of the fundamental nanoscale research with the progress in fabrication of realistic nanodevices. By bringing together the contribution of leading researchers from the materials science and SPM communities, relevant information is conveyed that allows researchers to learn more about the actual developments in SPM applied to functional materials. This book will contribute to the continuous education and development in the field of nanotechnology.

Download or read book Structure And Dynamics Of Heterogeneous Systems From Atoms Molecules And Clusters In Complex Environment To Thin Films And Multilayers written by Peter Entel and published by World Scientific. This book was released on 2000-05-11 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains contributions from cooperative research activities in physics and chemistry and addresses heterogeneous systems like atoms and molecules in complex environments, dye molecules like the retinal chromophore in the protein box of the human eye, interacting atoms/molecules in the interlayer of adsorbed structures, nucleation and domain formation processes in magnetic and martensitic systems. The particular aim of the contributions is to deduce the connection between different grades of heterogeneity and to bridge the gap between chemicals and heterogeneity on the atomic scale, and the physics of macroscopically heterogeneous systems. Besides the diverse experimental tools employed in the investigations, accompanying theoretical investigations range from ab initio molecular dynamics studies of the microscopic systems to Monte-Carlo simulations of the larger-scale problems.

Download or read book Optical and Electronic Process of Nano Matters written by Motoichi Ohtsu and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sizes of electronic and photonic devices are decreasing drastically in order to increase the degree of integration for large-capacity and ultrahigh speed signal transmission and information processing. This miniaturization must be rapidly progressed from now onward. For this progress, the sizes of materials for composing these devices will be also decreased to several nanometers. If such a nanometer-sized material is combined with the photons and/or some other fields, it can exhibit specific characters, which are considerably different from those ofbulky macroscopic systems. This combined system has been called as a mesoscopic system. The first purpose of this book is to study the physics of the mesoscopic system. For this study, it is essential to diagnose the characteristics of miniaturized devices and materials with the spatial resolution as high as several nanometers or even higher. Therefore, novel methods, e.g., scanning probe microscopy, should be developed for such the high-resolution diagnostics. The second purpose of this book is to explore the possibility of developing new methods for these diagnostics by utilizing local interaction between materials and electron, photon, atomic force, and so on. Conformation and structure of the materials of the mesoscopic system can be modified by enhancing the local interaction between the materials and electromagnetic field. This modification can suggest the possibility of novel nano-fabrication methods. The third purpose of this book is to explore the methods for such nano-fabrication.
