Abstract

Methods for solving crystalline nanostructures in real time at the electron microscope are reviewed, based on automated collection of microdiffraction patterns in three dimensions. We compare Koehler mode "SAD" patterns, a new kinematic CBED mode, and our new precession electron diffraction system. We discuss the optimum data-collection strategy and the eucentric-tilt problem. We advocate use of the new "charge-flipping" algorithm for solving the phase problem when dealing with relatively poor-quality electron diffraction data. We show an experimental demonstration of the effect of precession on the quality of diffraction data and of the use of the flipping algorithm to solve a nanocrystal.
