This interdisciplinary project will incorporate the disciplines of Physics, Chemistry, and Engineering. However the project is specifically housed within the Hope College Department of Physics.
AC electrochemical spectroscopy is a technique that can be used to determine the physical and chemical properties of a material by measuring the current response of the sample to an oscillating electric potential. Interpreting the results from this powerful technique involves careful modeling of the system being studied.
In this project, we will implement this measurement technique for in the Surface Lab and apply it to the characterization of energy storage materials. We will fabricate inorganic thin films with energy storage application using electrochemistry and characterize their structure, elemental composition, and capactitive (energy storage) behavior. Students will focus on AC electrochemical spectroscopy as a measurement technique, but will also learn to use and to interpret data from a number of different analysis tools, including scanning electron microscopy, and energy dispersive x-ray spectroscopy. Student will develop and implement protocols for AC spectroscopy meeasurements and for modeling and fitting the resulting data.
