Understanding of the single crystal diffraction

Reference no: EM131247101

Assignment:

You are to complete a lab report that will demonstrate your understanding of the single crystal diffraction with a four-circle x-ray diffractometer. This report should include a brief discussion of the four-circle x-ray diffraction method (both theory and practical aspects of recording the diffraction pattern). Follow the procedure above and address the questions given in bold text.

Additionally, draw a stereographic projection for (001)-and (101)-oriented single crystal SrTiO₃ including only the {100}, {110}, and {111} poles and discuss generally how the orientation affects diffraction with a four-circle x-ray diffractometer-for example, what are some reflections that are inaccessible using the techniques in this lab? Consider the stereographic projection for the (101)-oriented crystal, how many peaks would you expect to see in an in-plane (001) Φ scan?

Now consider that the SrTiO₃-crystal is cooled below 105K and undergoes a phase transition to a tetragonal crystal structure with lattice parameters a=b=3.897Å, c = 3.903Å. How does the (001) stereographic projection compare to the (100) stereographic projection at this temperature and how would this affect your in-plane Φ scan of the (101) plane as seen in step 9 for both (001) and (100) crystal orientations (i.e. how many peaks and why)?

In this lab we will look at three SrTiO3 single crystals with (001), (101), and (111) plane normal. We know that single crystal SrTiO3 has a cubic crystal structure with a lattice parameter ao = 3.905Å (JCP:35-0734). The first goal is to align the SrTiO3 crystal to all drives of the four circle diffractometer.
