Title: Aberration-Corrected Scanning/Transmission Electron Microscopy for Advanced Materials

Time: 10:00 - 11:00 AM, Monday, September 12, 2016

Place: Auditorium Room 410, HPSTAR (Shanghai)

Host: Dr. Wenge Yang


Abstract:

The advent of spherical aberration (Cs) correction has led to significant improvements in high-resolution scanning/transmission electron microscopy. Recent development of correction of chromatic aberration (Cc) offers a new opportunity to improve imaging capability further, allowing us to achieve amplitude contrast imaging (ACI) in high-resolution transmission electron microscopy. With these newly developed techniques, I will show some examples using aberration-corrected S/TEM for characterizing advanced materials such as catalysts, battery materials, ferroelectric films etc. Another example will be carbon materials such as graphene, and nanotubes, and high-pressure synthesized diamond.
