Determination of Oxygen Atomic Positions in a Ga–In–Sn–O Ceramic Using Direct Methods and Electron Diffraction

Abstract

Direct methods using dynamical transmission electron diffraction (TED) intensities is applied to the solution of (Ga,In)2SnO5. Dynamical diffraction effects in the TED data lead to an emphasis of oxygen positions in the structure. Application of direct methods to dynamical diffraction intensities represents a valuable new technique for obtaining approximate atom positions of light elements in ceramics using an experiment which is simple to perform and does not require a single crystal.
