Students use optical microscopy, x-ray diffraction, scanning electron microscopy, x-ray photoelectron spectroscopy, atomic force microscopy and other techniques to characterize recently discovered perovskite semiconductors that can be used to make highly efficient solar cells. This course fulfills the Writing in the Major Requirement for MSE undergrads. Instruction on writing, statistics, generating effective plots with curve fits, using databases to find information and giving oral scientific presentations is given. Instruction on characterization techniques is provided, but it is expected that the students will have already taken a course like MATSCI 153 that covers the fundamentals of the techniques. The emphasis on this course is on doing nanocharacterization experiments and writing up the results. Undergraduates register for 161 for 4 units; graduates register for 171 for 3 units.

Experimental x-ray diffraction techniques for microstructural analysis of materials, emphasizing powder and single-crystal techniques. Diffraction from epitaxial and polycrystalline thin films, multilayers, and amorphorous materials using medium and high resolution configurations. Determination of phase purity, crystallinity, relaxation, stress, and texture in the materials. Advanced experimental x-ray diffraction techniques: reciprocal lattice mapping, reflectivity, and grazing incidence diffraction. Enrollment limited to 20.

An introduction to the fundamental physical chemical principles underlying materials properties. Beginning from basic quantum chemistry, students will learn how the electronic configuration of molecules and solids impacts their structure, stability/reactivity, and spectra. Topics for the course include molecular symmetry, molecular orbital theory, solid-state chemistry, coordination compounds, and nanomaterials chemistry. Using both classroom lectures and journal discussions, students will gain an understanding of and be well-positioned to contribute to the frontiers of materials chemistry, ranging from solar-fuel generation to next-generation cancer treatments.
