Dear Allen, the simpack_xrd_InAs_fitting of course models a radial 2theta-omega scan. The documentation examples ( https://xrayutilities.sourceforge.io/simulations.html) also clearly specify that all models are for crystal truncation rod analysis (and are mostly tested for the symmetric 2theta-omega case). A pure 2theta scan would make not so much sense for an epitaxial system. so pure 2Theta scans can actually (somewhat limited) in xrayutilities only be simulated for powder/textured samples. So actually all "XRD" simulation examples are basically what you look for. I think the example file simpack_xrd_SiGe_superlattice.py could be particularly interesting since it shows also how a slightly more complex layer structure can be built. hope this helps Dominik |
