None ;
Prerequisites
1. Differential and Integral Calculus 2. Vector Analysis 3. Complex Analysis (Euler's Formula and the Complex Plane) 4. Elementary Electricity and Magnetism 5. Elementary Modern Physics (Atomic Energy Levels) 6. Atomic Bonding and Coordination
Description
Elementary crystallography. Basic diffraction theory; reciprocal space. Applications to structure analysis, preferred orientation. Diffractometer techniques with point detectors and 2D area detectors. Lectures, laboratory. Course Outcomes: 1. Students will be able to identify different types of crystal structures that occur in metals, ceramics, and polymers. 2. Students will be able to perform standard x-ray diffraction measurements on metals, ceramics and polymers and quantitatively interpret the results. 3. Students will attain an intermediate level of understanding for the particle and wave physical processes underlying x-ray emission, elastic and inelastic scattering, absorption, and interference of coherent waves. They will understand how these processes manifestly explain 3D and 2D kinematical diffraction, thin-film diffraction, conventional and synchrotron x-ray sources, x-ray fluorescence spectroscopy, and low-energy electron diffraction. 4. Students will understand how to use reciprocal space graphical constructions and vector algebra to interpret diffraction from 3D and 2D single crystals, and random and textured polycrystalline samples.
