Atomic force microscopy (AFM) is an amazing technique that allies a versatile methodology (it allows the imaging of samples in liquid, vacuum or air) to imaging with unprecedented resolution. But it goes one step further than conventional microscopic techniques; it also allows us to make measurements of magnetic, electrical or mechanical properties of the widest possible range of samples, with nanometre resolution. This book will demystify AFM for the reader, making it easy to understand, and easy to use. Peter Eaton and Paul West share a common passion for atomic force microscopy. However, they have very different perspectives on the technique. Over the past 12 years Peter used AFMs as the focal point of his research in a variety of scientific projects from materials science to biology. Paul, on the other hand, is an instrument builder and has spent the past 25 years creating these microscopes for scientists and engineers. This insightful book covers the theory, practice and applications of atomic force microscopes and will serve as an introduction to AFM for scientists and engineers that want to learn about this powerful technique, and as a reference book for expert AFM users. Application examples from the physical, materials, and life sciences, nanotechnology and industry illustrate the many and varied capabilities of the technique.Less

This chapter covers the background to AFM, placing it in the context of other microscopic techniques. It describes some major highlights of AFM, illustrating the power of the technique. It describes how AFM can be compared to optical and electron microscopy, and where AFM is a more suitable technique, and also where it is not. The AFM was developed as a version of the scanning tunnelling microscope (STM), that would be more capable of imaging biological samples; however AFM is now far more widely used than STM, and the chapter describes the development of AFM and STM, and shows why AFM is more popular for many samples.Less

Acoustic microscopy enables you to image and measure the elastic properties of materials with the resolution of a good microscope. By using frequencies in the microwave range, it is possible to make the acoustic wavelength comparable with the wavelength of light, and hence to achieve a resolution comparable with an optical microscope. The contrast gives information about the elastic properties and structure of the sample. Since acoustic waves can propagate in materials, acoustic microscopy can be used for interior imaging, with high sensitivity to defects such as delaminations. Solids can support both longitudinal and transverse acoustic waves. At surfaces a combination of the two known as Rayleigh waves can propagate, and in many circumstances these dominate the contrast in acoustic microscopy. Contrast theory accounts for the variation of signal with defocus, V(z). Acoustic microscopy can image and measure properties such as anisotropy and features such as surface boundaries and cracks. A scanning probe microscope can be used to detect ultrasonic vibration of a surface with resolution in the nanometre range, thus beating the diffraction limit by operating in the extreme near‐field. This 2nd edition of Acoustic Microscopy has a major new chapter on the technique and applications of acoustically exited probe microscopy.Less

Nanoscale scientific research suddenly arose during the 1980s and 1990s. It now constitutes an immense worldwide research domain. It is based on the invention of scanning probe microscopy and powerful numerical simulation, and on the capacity to manipulate individual molecules and atoms. The capacity of nanoscale research to synthesize artificial substances, often through epitaxy, such as fullerenes and low-dimensional objects, has fueled important transformations in scientific investigation and allowed the formulation of previously unimagined questions. The emergence of nanostructured materials and corresponding instrumentation has been fueled by cognitive, methodological, instrumental, and material combinatorials. “Combinatorial” refers to an association or interlocking of two or more components that give rise to a resulting novelty in the form of a synergy.Less

Polymer devices for electronic applications are generally prepared in thin film form and so the effect of surfaces is of significant interest. This chapter covers the thermodynamics of surfaces; different means of preparing thin films of relevance to polymer electronics; and the measurement of surfaces using scanning probe techniques or photoelectron analysis. In the latter case, the use of surface techniques to obtain information on the electronic properties of the material is discussed.Less

This chapter explains that the field of domain wall (DW) nanoelectronics is predicated on the premise that the distinct physical properties of domain walls offer new conceptual possibilities for devices. It first deals with basic physics of domain wall properties, and in particular the cross-coupling that allows domain walls to display properties and order parameters different from those of the parent bulk material. The chapter then turns to scanning probe techniques for measuring some of these domain wall properties, and specifically atomic force microscopy (AFM). Together with transmission electron microscopy, AFM is one of the most important tools currently available to probe and manipulate the individual position and physical properties of domain walls. Finally, the chapter focuses on two recent developments that allow investigating hitherto overlooked properties of domain walls: their magnetotransport and their mechanical response.Less

Polymer science is, of course, driven by the desire to produce new materials for new applications. The success of materials such as polyethylene, polypropylene, and polystyrene is such that these materials are manufactured on a huge scale and are indeed ubiquitous. There is still a massive drive to understand these materials and improve their properties in order to meet material requirements; however, increasingly polymers are being applied to a wide range of problems, and certainly in terms of developing new materials there is much more emphasis on control. Such control can be control of molecular weight, for example, the production of polymers with a highly narrow molecular weight distribution by anionic polymerization. The control of polymer architecture extends from block copolymers to other novel architectures such as ladder polymers and dendrimers. Cyclic systems can also be prepared, usually these are lower molecular weight systems, although these also might be expected to be the natural consequence of step-growth polymerization at high conversion. Polymers are used in a wide range of applications, as coatings, as adhesives, as engineering and structural materials, for packaging, and for clothing to name a few. A key feature of the success and versatility of these materials is that it is possible to build in properties by careful design of the (largely) organic molecules from which the chains are built up. For example, rigid aromatic molecules can be used to make high-strength fibres, the most highprofile example of this being Kevlar®; rigid molecules of this type are often made by simple step-growth polymerization and offer particular synthetic challenges as outlined in Chapter 4. There is now an increasing demand for highly specialized materials for use in for example optical and electronic applications and polymers have been singled out as having particular potential in this regard. For example, there is considerable interest in the development of polymers with targeted optical properties such as second-order optical nonlinearity, and in conducting polymers as electrode materials, as a route towards supercapacitors and as electroluminescent materials. Polymeric materials can also be used as an electrolyte in the design of compact batteries.
