Answering the need for fabrication specifications and analytical standards, this volume is the first complete source of information on the Kelvin probe. In surface engineering, the probe is considered the most powerful non-destructive technique used to understand active and passive surfaces and interfaces. While the equipment can be easily fabricated, until now engineers have lacked ready access to what this text provides: systematic documentation on design and fabrication. Just as significantly, this authoritative volume also explains how to interpret Kelvin probe data. It guides readers through the basics of design and builds their capacity for analysis through the use of case studies.
