摘要
Transmission electron microscopy (TEM) has recently become indispensable in determining crystal structures. The location of atoms in crystals can be determined using electron diffraction (ED) intensity data series if the diffracted intensities are directly proportional to the square of the structure factor (| F hkl | 2 ). However, due to the crystal thickness, the used electron wavelength and the potential misalignment of the measured crystal the detected intensities differ from the ideal values. A method, E lectron D iffraction I ntensity C orrection (EDIC), and a computer program have been developed to recover the ideal | F hkl | 2 proportional intensities from experimental data for kinematic scattering, for further structure studies.
