Transmission electron microscopes that use high-energy electrons are employed in many areas including the study of biology samples (like a virus) and nanoscience research and development (allow particles and carbon nanotubes, for example). A 3-MeV transmission electron microscope has been in operation in Osaka University in Japan for several years. The higher energy electrons allow for dipper sample penetration and extremely high resolution. What is the resolution limit for these electrons?
