Mineralogists, A friend of mine who is a chemist at our institution has an atomic force microscope in his research lab. These can image portions of crystal structures a few atoms across! He has invited my mineralogy students to stop by for a demo with some easily-cleaved minerals from our collection. Do any of you have experience with AFM? I'm wondering which minerals might be best suited for this technique. I would like to reinforce what they have learned about mineral crystal structures earlier in the semester. Thank you!
