Experimental variation of contrast in HREM imaging with FFIM mode Off (3a) and On (3b). Note the reduction of the superimposed Fresnel illumination contrast and the negligible effect on the local image contrast.

Acquisition of EDS maps with rocking beam using combination of AutoScript and Velox

Special thanks for the script to Fumihiko Uesugi, National Institute for Materials Science, Tsukuba-shi Ibaraki, Japan.

For application also see Direct Mapping of Fluorine in Cation Disordered Rocksalt Cathodes by Krishna Prasad Koirala, Lin Jiang, Shripad Patil, Paolo Longo, Zhao Liu, Bert Freitag, Juri Barthel, Ethan C. Self, Yingge Du, Lee Pullan, Ted Tessner, Leslie J. Allen, Wu Xu, Wei Tong, Jagjit Nanda, and Chongmin Wang

Supported HW: Spectra, Talos. Velox 3.12 or higher.

AutoScript 1.5 and higher.

Comparison of compositional mapping and rocking beam technique. In mapping the beam is moved across the
area of interest (left) while in rocking beam mode the stationary beam s tilted in both directions on the specimen (right).

Three rocking beam maps on STO in {100} projection with different tilt ranges (half angle of 40,60,80mrad)
are shown to illustrate the maximum tilt range (upper and middle graphs). The intensity ratio map of Sr/O and
Ti/O ICP (bottom images) reveal the elemental ratio changes with different beam to crystal orientation, which
can influence quantitative compositional analysis. (Channeling)
