Abstract

We established a method for site-selective electronic structure analysis, using TEM-EELS under electron channeling (standing-wave) conditions and first-principles band calculations. In particular, we applied a self-modeling curve resolution (SMCR) technique to separate a set of experimental spectra into individual spectra of individual atomic sites. A case study is presented for Al-K ELNES in oxide ceramics, which shows spinel and garnet structures containing two types of Al sites.
