Title: Temporal and thermal evolutions of surface Sr-segregation in pristine and atomic layer deposition modified La 0.6 Sr 0.4 CoO 3−δ epitaxial films

The bulk-to-surface Sr segregation vs. temperature and time in La 0.6 Sr 0.4 CoO 3−δ have been studied. The atomic fraction of surface-Sr was effectively reduced by atomic layer deposition of ZrO 2 overcoat.
