| Research Abstract |
We have developed an apparatus for making a localized evanescent field spot on a specimen equipped in a transmission electron microscope. We have applied the apparatus for evaluating an optical response of dislocations in ZnO crystals, and revealed that screw dislocations in ZnO have a localized energy level of about 2.5eV in depth.
