摘要
通过脉冲激光沉积法在 SrTiO3 单晶衬底的 (210) 表面生长出了 Ba2Ti6O13 单晶薄膜。扫描透射电子显微镜显示，Ba2Ti6O13 薄膜是外延生长的，Ba2Ti6O13 的 a 轴和 b/c 轴分别平行于 (210) 平面和 SrTiO3 的 [00-1]/[-120] 方向。Ba2Ti6O13 薄膜的电导率比缺氧约为δ = 0.05 的还原型 SrTiO3-δ 单晶大约大一个数量级。电子结构计算表明，δ 是一种 n 型变质半导体，主要具有钛 3d 轨道的自旋分裂态。
Pulsed laser deposition and structural analysis of Ba2Ti6O13 epitaxial thin film on the (210) surface of SrTiO3 single crystal
A single crystalline thin film of Ba2Ti6O13 was grown on the (210) surface of a SrTiO3 single-crystal substrate by pulsed laser deposition. Scanning transmission electron microscopy shows that the Ba2Ti6O13 thin film grew epitaxially with the a-plane, and the b-/c-axes of Ba2Ti6O13 parallel to the (210) plane and the [00-1]/[-120] directions of SrTiO3, respectively. The electrical conductance of the Ba2Ti6O13 film was approximately one order larger than that of reduced SrTiO3-δ single crystal with oxygen deficiency of roughly δ = 0.05. Electronic structure calculations predict that δ is an n-type degenerate semiconductor with spin-split states primarily of Ti 3d orbital.
