My project is still going good so far. I have been able to work the Transmission Electron Microscope(TEM) without much difficulty and collected diffraction patterns from a gold sample. I am currently analyzing the diffraction patterns from the LSMO and gold samples. I am compiling possible explanations for some of the pattern characteristics, such as halos and extra spots, in the LSMO. Comparing the LSMO patterns to the gold patterns, which seems to be amorphous, can give clues about some of the LSMO pattern characteristics. So far, some of the explanations that are related to what I have observed are superlattice reflections, reflections from defects, and crystalline-amorphous transition. I will continue to look for possible explanations and index the LSMO pattern.
The Field Museum trip was fantastic! It was a nice break from research. However, there was still a lot of relevant information in the museum. The Bio-Luminescence exhibit showed a lot of diagrams on diffraction and reflection of light, which are important concepts in my project. All of the other exhibits where very interesting as well. I made sure to take lots of pictures to remember this great excursion!
