Nanoscale stoichiometric analysis of a high-temperature superconductor by atom probe tomography

The functional properties of the high temperature superconductor Y1Ba2Cu3O7- (Y-123) are closely correlated to the exact stoichiometry and oxygen content. Exceeding the critical value of 1 oxygen vacancy for every 5 unit cells ( > 0.2, which translates to a 1.5 at.% deviation from the nomi...
