Electron Transfer In Nanomaterials

This book reviews research on single-electron devices and circuits in silicon. These devices provide a means to control electronic charge at the one-electron level and are promising systems for the development of few-electron, nanoscale electronic circuits. The book considers the design, fabrication, and characterization of single-electron transistors, single-electron memories, few-electron transfer devices such as electron pumps and turnstiles, and single-electron logic devices. A review of the many different approaches used for the experimental realisation of these devices is provided and devices developed during the author''s own research are used as detailed examples. An introduction to the physics of single-electron charging effects is included. Sample Chapter(s). Chapter 1: Introduction (301 KB). Contents: Introduction; Single-Electron Charging Effects; Single-Electron Transistors in Silicon; Single-Electron Memory; Few-Electron Transfer Devices; Single-Electron Logic Circuits. Readership: Researchers, academics, and postgraduate students in nanoelectronics, nanofabrication, nanomaterials and nanostructures, quantum physics and electrical & electronic engineering.

Over the past few decades, several approaches have been developed for designing nano-structured or molecularly-structured materials. These advances have revolutionized practically all fields of science and engineering, providing an additional design variable, the feature size of the nano-structures, which can be tailored to provide new materials with very special characteristics. Nanomaterials: Design and Simulation explores the role that such advances have made toward a rational design of nanostructures and covers a variety of methods from ab initio electronic structure techniques, ab initio molecular dynamics, to classical molecular dynamics, also being complemented by coarse-graining and continuum methods. Also included is an overview of how the development of these computational tools has enabled the possibility of exploring nanoscopic details and using such information for the prediction of physical and chemical properties that are not always possible to be obtained experimentally. * Provides an overview of approaches that have been developed for designing nano-structured or molecularly-structured materials. * This volume covers several aspects of the simulation and design of nanomaterials analyzed by a selected group of active researchers in the field. * Looks at how the advancement of computational tools have enabled nanoscopic prediction of physical and chemical properties
