Imaging and controlling nanoscale crystal growth in the transmission electron microscope — •Frances M. Ross — IBM T. J. Watson Research Center, Yorktown Heights, NY, USA

Building functional nanostructures with atomic level precision requires a detailed understanding of materials growth and the physics of self-assembly at the nanoscale. In situ imaging in the transmission electron microscope can provide unique information here, because measurements can be made on individual nanostructures while they grow. Here we will describe examples in which in situ electron microscopy helps to explore growth mechanisms and can even suggest strategies to build new types of structure. We will show nanocrystal epitaxy on graphene, electrochemical deposition processes in aqueous solutions and the formation of semiconductor structures from catalytic droplets. We will conclude with a perspective on the exciting recent developments in electron microscopy and how these will advance in situ experiments in the future.
