Heterogeneous Structure of Amorphous Materials

Abstract

Heterogeneous structure with different electron density distribution has been proposed from the data of the extended X-ray absorption fine structure (EXAFS) and the small angle X-ray scattering (SAXS) in an amorphous Fe 0.9 Zr 0.1 alloy, an amorphous GeSe semiconductor and an amorphous PbTiO 3 dielectric quenched from the melts. The local structures and the density correlations in the above three materials were determined.
