A material that is currently being used in a cutting edge energy -related device such as a solar cell, battery or smart window will be thoroughly characterized throughout the quarter. Fabrication techniques could include electroplating, spin coating and thermal evaporation. There will be an emphasis in this course on characterization methods such as scanning electron microscopy, x-ray photoelectron spectroscopy, atomic force microscopy, optical microscopy, four-point probe measurements of conductivity, visible absorption and reflection spectroscopy and electrochemical measurements (cyclic voltammetry). Devices will be fabricated and their performance will be tested. In this Writing in the Major course, students will put together all of the data they collect during the quarter into a final paper.
