What Can You Do with XRD? Identify and Quantify Phase Composition TiO 2 - Rutile TiO 2 - Anatase TiO 2 - Brookite Rutile: P4 2 /mnm high temperature polymorph white pigment, sunscreen, UV-blocking coatings, photovoltaic Anatase: I4 1 /amd semiconductor, photocatalyst, antimicrobial coating, oxygen sensor Brookite: Pcab no known use
3
Other Things to Do with XRD Data Measure Unit Cell Lattice Parameters Estimate Crystallite Size and Microstrain Measure Residual Stress (macrostrain) Measure Texture or Epitaxy Evaluate Thin Film Quality Determine Crystal Orientation Determine Crystal Structure
4
Diffraction Techniques Available at the CMSE X-Ray Powder Diffraction (XRPD) Grazing Incidence Angle Diffraction (GIXD) Pole Figure Mapping Microdiffraction ( XRD) Residual Stress Mapping In situ XRD from 11K to 1473 K Reciprocal Space Mapping Single Crystal Diffraction (SCD) Back-Reflection Laue X-Ray Reflectivity (XRR) Small Angle X-Ray Scattering (SAXS)
5
Getting Access to XRD Training for Self-Use Requires 1 hour X-ray Safety Course from EHS 1 hour Lab Specific Safety Training 2 hr Instrument Specific Training 2 hr Practical XRD Lecture next session: June 21, 10 am to 5 pm
6
Getting Access to XRD Also Recommended for Self-Users: Basic XRD Data Analysis using Jade software 1:30 to 4 pm on June 26 or June 27 additional dates scheduled according to demand Assisted Use is also Available usually needs to be scheduled ~2 weeks in advance
