Basic Impedance Spectroscopy

摘要

This course is intended for chemists, physicists, materials scientists, and engineers with an interest in applying electrochemical impedance techniques to study a broad variety of electrochemical processes. The attendee will develop a basic understanding of the technique, the sources of errors in impedance measurements, the manner in which experiments can be optimized to reduce these errors, and the use of graphical methods to interpret measurements in terms of meaningful physical properties. The topics to be covered include: 1. The motivation for using impedance spectroscopy advantages as compared to other transient techniques and the conditions under which its use is ideally suited, 2. The basic concepts of how impedance is measured
