Domino phase retrieval algorithm for structure solution

Abstract

Novel domino-fashion-algorithm method for structure determination is being aimed to general solution of the phase retrieval problem, consequently combining the electron diffraction (ED) and the high-resolution transmission electron microscopy (HRTEM) patterns. The fusion of the direct-method technique that is described here allows realization of a full-phase restoration of complex structure factors. A numerical example, using the dynamical ED and HRTEM input data for (Ga,In)2SnO5 ceramic, shows that the method is capable of yielding unique phase retrieval solution. The clear sense is that the domino-fashion algorithm presented does work well and it is a valuable method for phasing diffraction patterns experimentally observed in electron crystallography provided that collecting the ED and HRTEM data have been consequently carried out. © 2012 Springer Science+Business Media Dordrecht.
