Although the emphasis is on the scattering of x-rays, the kinematical formalism developed is applicable to the scattering of electrons and neutrons as well. The dynamical theory of diffraction is not treated. Emphasis is on the application of scattering/diffraction to the structural characterization of materials. TOPICS COVERED 1. Review of the properties of x-rays; crystallography; reciprocal lattice; stereographic projection 2. Diffraction Geometry Bragg’s law; Laue’s equations; diffraction and the reciprocal lattice; diffraction methods; etc. 3. Diffraction Intensities Scattering by electrons, atoms, unit cells; structure factor; polycrystals; multiplicity factor; Lorentz factor; absorption factor; temperature factor; etc. 4. Diffraction - Real Samples Grain size effects; strain effects; 5. Diffractometer Measurements 6. Phase Identification 7. Determination of Crystal Structure 8. Quantitative Phase Analysis 9. Precise Parameter Measurement* 10. Structure of Polycrystalline Materials* 11. Stress Measurement* 12. Crystal Quality* 13. Small Angle Scattering* 14. Electron Diffraction* 15. Neutron Diffraction* * Time permitting (order may change) GRADING: Midterm Exams: There will be two midterm exams, each of which will count for 20% of the course grade. Final Exam: The final exam will be comprehensive and will count for 40% of the course grade. Missed exams can be made up for excused absences only. Please inform the instructor if you know you will miss an exam in advance. Unexcused absences on quiz/exam days will result in a grade of zero on the quiz/exam missed. Homework: Periodic homework assignments will count for 20% of the course grade. Homework submitted past the due date will be assigned a grade of zero. ATTENDANCE POLICY: Students are encouraged to attend lectures and are responsible for all material presented in class. Class attendance will not be recorded. ACADEMIC INTEGRITY Students are encouraged to study together (including working together on the homework assignments). If you simply let someone copy your homework assignment, rather than working with them on it, you will be doing neither of you a favor. Students are to neither receive nor give help to others during exams. Any student suspected of academic misconduct will be referred to the Office of Student Integrity.
