Postdoctoral position, High Definition Electron Microscopy - 2019BAPFWETEF132Posted by: University of Antwerp
Posted date: 2019-May-07
The EMAT research group at the Faculty of Science (University of Antwerp) is seeking to fill a
Postdoc position in the area of “High Definition Electron Microscopy: Greater clarity via multidimensionality”
under the supervision of Prof. Timothy Pennycook.
This vacancy is situated in the H2020 ERC Starting grant High Definition Electron Microscopy: Greater clarity via multidimensionality (HDEM). The overarching goal of the HDEM project is to maximize the amount of information retrieved per unit dose via multidimensional data acquisition and analysis techniques such as 4D STEM and optical sectioning.
We have recently shown via image simulations that electron ptychography can significantly outperform the dose efficiency of HRTEM, offering the prospect of significantly extending the capabilities low does imaging and of cryo-EM. To realize the potential of ptychography for low dose imaging experimentally we will utilize the latest in high speed cameras to record the required 4D STEM datasets. We will combine our enhanced imaging capabilities with single particle analysis for imaging biomolecules at ultra low doses. Similar techniques will be used for fragile materials science samples, for instance metal organic framework, Li ion battery, 2D, catalyst and perovskite solar cell materials. In addition to ultralow dose work, we aim to investigate extending our capabilities for high precision applications including imaging local electromagnetic fields, determining the location of light atoms within a heavy lattice and testing the limits of imaging directly in 3D.
