Phase & Orientation mapping at the nm scale using 4D
SPED in TEM
September 22nd, 2021
16:00 - 17:30
Faculty of Civil and Industrial Engineering - Sapienza University of Rome
The satellite event during NanoInnovation 2021, will cover an introduction to Precession enhanced Phase & Orientation mapping for TEM (4D-Scanning Precession Electron Diffraction – 4D-SPED*). ASTAR is like the traditional EBSD method in SEM, and the major benefit is the spatial resolution that can be up to 1-3 nm (in case of FEG-TEM). Such resolution makes the application unique, able to shed light to local properties of materials, like thin films, metals, batteries, ceramics, semiconductors, nanoparticles, etc.
Recent examples of ASTAR will be presented. We hope you take this opportunity to learn about this advanced technique for TEM and visualize the wide range of exciting results obtained by 4D-SPED (ASTAR).
