The book Characterization of Nanostructures outlines the most widely used techniques and methods that apply to nanostructures and discusses typical applications to single nanoscale objects, as well as to ensembles of such objects. The book is divided into two parts: In the six chapters in Section I: Techniques and Methods an overview is given of the physical principles of the main techniques, and a description of those operational modes that are most relevant to nanoscale characterisation. The book provides sufficient technical detail so that readers and prospective users can gain an appreciation of the strengths and limitations of particular techniques. The chapters deal with both mainstream and less commonly used techniques. The five chapters in Section II: Applications of Techniques to Structures of Different Dimensionalities and Functionalities deal with the methods for materials characterisation of generic types of systems. Each chapter begins with a brief description of the materials and supplies a context for the methods for characterisation. The volume concludes with a series of flow charts and brief descriptions of tactical issues.
