Abstract:

Vacancy type defects in La0.5Sr0.5CoO3/Pb0.9La0.1Zr0.2 Ti0.8/La0.5Sr0.5CoO3 capacitors were investigated by positron depth profiling. Post-growth annealing of the capacitor structure in oxygen deficient atmosphere exhibits the formation of vacancy type defects in all layers. A significant increase in open volume defects was found in the top and bottom electrode. The changes in the bottom electrode were studied more closely by etching off the top layer.
