Abstract

Transmission Electron Microtomography (TEMT) is a powerful tool to observe the three-dimensional (3D) nanostructures of the sample. It is known that Electron Energy Loss Spectroscopy (EELS) allow us to distinguish the specific elements and is effective for the light elements. When the TEMT is combined with EELS, the 3D elemental maps would be acquired. The Indium map (In map) of Indium colloid (This is model system.) was acquired using three-window method. Then the focus-shift was calibrated and the slit width of the energy-filter was expanded to increase the number of electrons at the detector. As the result of such the improvement, the In map with little noise and high contrast could be acquired in a short time. The same procedure will be tested on a polymeric sample, which will be reported at the conference time.
