Ultrafast Atomic Layer-by-Layer Oxygen Vacancy-Exchange Diffusion in Double-Perovskite LnBaCo(2)O(5.5+δ) Thin Films

Surface exchange and oxygen vacancy diffusion dynamics were studied in double-perovskites LnBaCo(2)O(5.5+δ) (LnBCO) single-crystalline thin films (Ln = Er, Pr; −0.5 < δ < 0.5) by carefully monitoring the resistance changes under a switching flow of oxidizing gas (O(2)) and reducing gas (H(2))...
