Acoustic Scanning Probe Microscopy: An Overview

Chapter
Part of the NanoScience and Technology book series (NANO)

Abstract

In this chapter, which serves as an introduction to the entire book, an overview is given of techniques resulting from the synergy between ultrasonic methods and scanning probe microscopy (SPM). Although other acoustic SPMs have been developed, those reviewed in this book are either the earliest proposed techniques, which are most widespread, extensively used, and continuously improved, or have been recently developed, but have been proved to be extremely promising. The techniques are briefly introduced, emphasizing what they have in common, their differences, their capabilities, and limitations.

Keywords

Atomic Force Microscopy Scanning Probe Microscopy Contact Stiffness Magnetic Force Microscopy Atomic Force Microscopy Cantilever 
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

Notes

Acknowledgments

Donna C. Hurley is kindly acknowledged for the detailed critical revision of the chapter. Andrea Bettucci and Marco Rossi are acknowledged for useful discussions and suggestions.
