Applications of Linear and Nonlinear Dielectric Spectroscopy

Dielectric relaxation spectroscopy has provided an enormous body of information on the dynamics and structure of liquids, supercooled liquids, and glasses. Covering the range of about 20 orders of magnitude in time or frequency, very different types of materials can be studied, which translates into a large temperature window across which relaxation processes can be observed. Due to the high resolution of this technique, subtle residual mobility of molecules in glasses and very thin films can be measured.
This talk will give a survey of the very different and insightful applications of both linear and nonlinear dielectric techniques. Topics will include characterizing dynamics of supercooled liquids, assessing heterogeneity of liquid dynamics, probing the role of hydrogen bonding in forming supramolecular structures, and watching film growth during physical vapor deposition.
