Abstract

The new JEM-2010FEF electron microscope provides useful techniques based on energy filtering as an omega-type energy filter is integrated into a thermal field-emission 200 kV transmission electron microscope. For example, the zero-loss imaging improves the contrast of high resolution lattice images as well as images of precipitates or lattice defects in alloys. The acquisition time for elemental mapping with core-loss electrons is one order in magnitude shorter than with energy-dispersive X-ray spectroscopy. The removal of inelastically scattered electrons enables us to observe weak lines in convergent-beam electron diffraction patterns from a thicker specimen with a probe size 1-2 nm in diameter. A combination of the field emission gun and sensitive recording media such as an imaging plate and a slow-scan CCD camera makes the energy filtering more powerful.
