Formation of lanthanum strontium cobalt thin films by metalorganic decomposition

Electrically conductive films of La0.5Sr0.5CoO3, 1 μm thick, were formed on a variety of substrates by metalorganic decomposition. The lowest resistivity films (1.2×10−3 Ω cm) were obtained on c-axis sapphire by annealing in oxygen at 800 °C. The film conductivity was limited by the diffusion of str...

Description
Summary:Electrically conductive films of La0.5Sr0.5CoO3, 1 μm thick, were formed on a variety of substrates by metalorganic decomposition. The lowest resistivity films (1.2×10−3 Ω cm) were obtained on c-axis sapphire by annealing in oxygen at 800 °C. The film conductivity was limited by the diffusion of strontium into the substrate.
