The retrieval of a unique crystal potential from the scattering matrix {\cal S} in high-energy transmission electron diffraction is discussed. It is shown that, in general, data taken at a single orientation are not sufficient to determine all the el

The validity domain of a recently proposed iterative scheme for the inversion of the wavefunction of fast electrons after dynamical diffraction in a crystal, which is based on reversal of the multislice algorithm, is investigated by Bloch wave analys

A possible method for obtaining the crystal potential by inversion of the complex wavefield at the exit surface of the specimen, based on reversal of the multislice algorithm, is outlined. Results from preliminary testing of the method using computer

The tuned-voltage effect occurs when zone-axis diffraction emulates symmetrical-two-beam conditions. The nature of the tuned-voltage effect is examined in detail from both the Bloch wave and physical optics (multislice) methods. These methods delinea

Based on previous work, a knowledge of the defect structures created in diamond is crucial for optimizing the doping of diamond by ion irradiation. In the present work, type Ha diamond has been irradiated with 320keV Xe ions at room temperature. It w

1. IntroductionSeveral methods of phase retrieval from HRTEM image intensity distributions have been proposed but no standard method has emerged. We report on the results achieved using a technique based on a development of the “focus variation met

Several examples of the image-matching technique in HRTEM, involving the detailed comparison of experimental and computer-simulated images, are described. These illustrate the essential difficulty of the exercise and give some guiding criteria for im
