Abstract

High-resolution Z-contrast imaging in the scanning transmission electron microscope (STEM) forms an incoherent image where changes in atomic structure and composition across an interface can be interpreted intuitively. Parallel detection energy loss spectroscopy (PEELS) can be used simultaneously to provide complementary chemical information on an atomic scale. The fine structure in the PEEL spectra can be used to investigate the local electronic structure and the nature of the bonding across the interface. The complimentary techniques of high resolution Z-contrast imaging and PEELS are used in investigating the atomic structure and chemistry of a 25 degree symmetric tilt boundary in a bicrystal of the electroceramic SrTiO3.
