Performance of Ultrahigh Resolution Electron Microscope JEM-4000EX and some Applications of High Tc Superconductor

Abstract

The high resolution electron microscope is powerful for modern materials science, because of its direct observation capability for the atomic structure of materials. The JEM-4000EX, a 400 kV accelerating voltage electron microscope whose objective lens has a 1 mm spherical aberration coefficient, has a 0.168 nm theoretical resolving power. Using this microscope, atomic structure images of high Tc superconductor such as Y-Ba-Cu-O, Bi-Ca-Sr-Cu-O and Tl -Ca-Ba-Cu-O were observed.
