The Nanoscale and Microscale Research Centre is pleased to announce that Dr Christopher Allen from Diamond Light Source will be presenting on Ptychography: A New Era in Electron Imaging on Wednesday 23rd June, 15:00-16:00, in X1 Chemistry Building and Microsoft Teams.
The latest generation of fast, direct electron detectors have been a catalyst for the development of novel electron imaging techniques based on the collection and analysis of large numbers of diffraction patterns.
At the forefront of these new techniques is electron ptychography, a diffraction imaging technique in which the phase of the electron wave function can be quantitatively recovered.
Electron ptychography can surpass the standard resolution limits of electron microscopy and has been shown to be very dose efficient opening up the possibility for the study of the atomic structure of materials which could not previously be imaged. Furthermore the quantitative nature of the phase recovery allows for the imaging of internal electro-magnetic fields and local variations in charge density at sub-Angstrom resolution.
In 2016 Dr Christopher Allen moved to the electron Physical Sciences Imaging Centre (ePSIC) at Diamond Light source as a Staff Scientist and became Principal Scientist in 2019. Chris' current research is focused on technique development for low voltage STEM, TEM and diffraction imaging of low dimensional and beam sensitive materials.
