摘要

Our study of electron crystallography or convergent beam electron diffraction (CBED) and of electron spectroscopy or electron energy-loss spectroscopy (EELS), which were done from my student time until my retirement, is described together with other important results. All the crystal point groups can be determined unambiguously by CBED. Most crystal space groups are determined by using dynamical extinction effect and coherent CBED. The large angle technique enables us to determine the characteristic features of the lattice defects more reliably than the traditional electron microscope method. Using the energy filtering technique, the crystal structure refinement is successfully carried out by fitting the experimental CBED pattern with the theoretically calculated pattern. A case study of the determination of a charge density distribution is shown. A high energy resolution EELS instrument (<0.1 eV) was developed for the study of electronic structures or the structure of the conduction band. A case study of a detailed band structure is shown with a theoretical calculation. A clean application to fullerenes is shown. A recent development of the wavelength dispersive spectroscopy attachment is mentioned.
