關於本電子書

Techniques of nanoscale functional imaging and spectroscopy have blossomed since the invention of scanning probe microscopy (SPM) tools, starting with scanning tunneling microscopy in the early 1980s. The ability to resolve topographical features with nanoscale—sometimes atomic—precision has revolutionized our understanding of molecules, matter, and living systems. These observations have led scientists to pose increasingly more complex questions about properties beyond morphology and their evolution upon external stimuli. Overall, SPM-based schemes provide versatile ways to probe structural, electrical, mechanical, and chemical properties of materials at the nanoscale.

Getting started with SPM can be intimidating. This digital primer aims to provide undergraduate and graduate students majoring in various fields of science and engineering with a practical guide to grasp essential concepts and principles related to SPM image and spectra formation and their interpretation. This guide may also be helpful to researchers who are considering new ways of evaluating nanoscale properties of materials, devices, or living systems as applicable to their respective fields. Because of the extensive literature on the developments and applications of SPM, it was impossible to comprehensively cover all aspects of the field. Hence, deliberate choices were made to emphasize some techniques that have not been discussed as extensively in the literature but hold great promise to understand complex systems at the nanoscale.
