Domino phase retrieval algorithm for structure determination using electron diffraction and high resolution transmission electron microscopy patterns

Direct method formalism to determine atomic structures using the electron diffraction data is here aimed at a general solution of the phase retrieval problem, consequently combining the electron diffraction (ED) and the high-resolution transmission electron microscopy (HRTEM) patterns in a "dom...
