A single crystalline thin film of Ba _2 Ti _6 O _13 was grown on the (210) surface of a SrTiO _3 single-crystal substrate by pulsed laser deposition. Scanning transmission electron microscopy shows that the Ba _2 Ti _6 O _13 thin film grew epitaxially with the a -plane, and the b -/ c -axes of Ba _2 Ti _6 O _13 parallel to the (210) plane and the [00 $\bar{1}$ ]/[ $\bar{1}$ 20] directions of SrTiO _3 , respectively. The electrical conductance of the Ba _2 Ti _6 O _13 film was approximately one order larger than that of the reduced SrTiO _3− _δ single crystal with oxygen deficiency of roughly δ = 0.05. Electronic structure calculations predict that Ba _2 Ti _6 O _13 is an n-type degenerate semiconductor with spin-split states primarily of Ti 3d orbital. |
