Transmission electron microscopy study on the local structure and structural evolution in disordered materials

Jeudi 28 mai 2015 à 14h00 C.S.N.S.M. - Bât. 108 - Salle de réunion

Detailed investigation on the structure and structural alteration of solids at the atomic scale is of importance for understanding the nature of matter and for realizing desirable material properties. Transmission electron microscopy is a powerful tool to extract the local structural information both in real and reciprocal spaces through the use of particle and wave characteristics of the electron. However, analysis for disordered solids such as amorphous materials remains challenging despite a recent development of imaging techniques. Classical radial distribution function analysis combined with electron diffraction is one of the useful ways to characterize atomic correlation in amorphous networks. This seminar will present the results of our investigation on the local structure and structural alternation in nanostructured disordered materials. A brief review of the advantage of electron diffraction for analyzing short-range order of amorphous materials will be also presented.
