This introductory text deals with how electric currents behave at the nanometer scale. The book ties together several aspects of recent research on current flow at the nanoscale, including its relevance in defects, grain boundaries, tunneling, and atomic contacts; its effects through nanostructures, particularly for transistor miniaturization; and the techniques used to probe currents and voltages at the nanoscale, focusing on scanning probe microscopy and transport measurements. It covers topics such as quantum transport, mesoscopic physics, and molecular electronics, among others.Unlike...

This second edition of the book, initially written as an introductory text dealing with how electric currents behave at the nanometer scale, begins with a general description of electric currents at the macroscale. Then by considering the physical lengthscales relevant to electron flow, it is observed how the behavior of currents varies as they approach the nanoscale. A quantum description of electric current is covered as well as its relevance, with particular reference to defects, grain boundaries, tunnelling and atomic contacts, followed by the effects of current flow through...

Nanotechnology is a buzz word many of us have heard but are uncertain what it really means. This book works to dispel the myths and unravel the truth about this branch of science and technology that has already touched many aspects of our lives, from cheaper and faster medical diagnostic tools and more effective ways to deliver existing ones to helping to create new medicines and electronic devices.Size Really Does Matter starts by looking at the science and history of nanotechnology, followed by real-life examples of how it is used, what cutting-edge research is being carried out and why,...
