Defect Identification in (La, Sr)CoO3−δ Using Positron Annhiiilation Spectroscopy
Abstract
Vacancy type defects in bulk La1−xSrxCoO3−δ samples were investigated by positron lifetime spectroscopy. The effects of Sr-doping as well as the effect of oxygen deficiency were determined. Comparing the resolved lifetimes with calculated values permits defect identification.
