Abstract

High-spatial resolution energy-dispersive x-ray spectroscopy (EDX), electron energy loss spectroscopy (EELS) and CBED techniques with a 20 angstroms field emission probe were used to quantitatively analyze YBa2Cu3O7-δ. The geometry of arbitrary grain boundaries was modeled using the constrained Coincidence Site Lattice (cCSL) theory. Quantitative measurements of lattice parameters and of oxygen/hole content at the boundary regions were made. The oxygen/hole density was quantified by Gaussian fitting to the observed oxygen K-edge spectra and comparing them with those from the same batch which had undergone oxygen reduction process. Oxygen content was determined by thermal gravimetric analysis and mass-measurement techniques.
