2018 Albert Crewe Award

Timothy Pennycook
Max Planck Institute for Solid State Research

Timothy J. Pennycook is a research scientist at the Max Planck Institute for Solid State Research in Stuttgart, Germany, working to develop new techniques in aberration corrected scanning transmission electron microscopy (STEM). He received his PhD in Physics from Vanderbilt University in 2012, combining density functional theory with STEM to investigate materials, uncovering the origin of colossal ionic conductivity in yttria-stabilized zirconia and, using dynamic STEM imaging, revealing the origin of white light emission from ultrasmall CdSe nanoclusters. As a Research Fellow with the University of Oxford, based at the SuperSTEM laboratory in Daresbury, he developed 3D spectroscopic imaging with optical sectioning, quantification of the atomic scale dynamics involved in solid state phase changes, and a new method of high efficiency ptychography for phase contrast imaging. In 2014 Pennycook joined the Faculty of Physics, University of Vienna, using STEM to study 2D materials, and in 2015 was awarded a Marie-Sklodowska-Curie Individual Fellowship to continue his research into ptychography. He has shown that electron ptychography offers not only the highest efficiency imaging in STEM, but also gives double resolution and much greater robustness to temporal incoherence than high resolution transmission electron microscopy, revealing a new route to low dose imaging of beam sensitive materials. In 2017 he moved to Stuttgart to further develop these techniques.
