Abstract

3-dimensional observation on the atomic arrangement and atomic species in a thin-film specimen are carried out at high speed and accuracy by an electron microscope which measures electrons emitted at high angle from the specimen. A scanning transmission electron microscope has an electron detection device comprising a scintillator converting electrons detected thereby to photons, a photoconductive-film converting photons from the scintillator detected thereby to c.a. 1000 times as many electron-hole pairs as these photons.
