| Outline of Final Research Achievements |
Recent reports say that energy selective detection of low loss electrons (LLEs) enables us to observe surface and material sensitive images in scanning electron microscopy (SEM). The auther studied the image formation mechanisms of this LLE images taking titania nano film on Si substrate as a model specimen. The backscattering electron images taken with various energy detection conditions were compared with energy spectra of the specimen measured by electron analyzer. As a result, this study revealed that electrons, whose energy is about that of plasmon loss energy, play important role to give strong contrast to the nano film in SEM-LLE image formation.
