The Opensource Handbook of Nanoscience and Nanotechnology

Nanotechnology and nanoscience is about controlling and understanding matter on the sub-micrometer and atomic scale.

This wikibook on nanoscience and nanotechnology gathers information about the various tools, methods and systems to provide students, researchers and everyone else an open-source handbook and overview guide to this vast interdisciplinary and expanding field - a book that can be adjusted as new things appear and improved by you!

Chapter 1: Introduction

Why is nanotechnology such a 'hot' subject - and is it more hype than substance? This part gives a brief introduction to the visions of nanotechnology and why so many people are working on it around the world. To help set a perspective there are overview tables with timelines, length scales and information resources.

Chapter 2: Seeing 'Nano'

Microscopes allows us to probe the structure of matter with high spatial resolution, making it possible to see for instance individual atoms with tools such as the scanning tunneling microscope, the atomic force microscope, and the transmission electron microscope. With the related spectroscopic methods, we can study the energy levels in nanosystems. This part gives an overview of the tools and methods used in microscopy and spectroscopy of nanostructures.

Chapter 3: Physics at the Nanoscale

On the nanoscale force that we in everyday life do not consider strong, such as contact adhesion, become much more important. In addition, many things behave in a quantum mechanical way. This chapter looks into the scaling of the forces and fundamental dynamics of matter on the nanoscale.
