采用脉冲激光气相沉积(PLD)技术在MgO(100)衬底上生长了Co/BaTiO3纳米复合薄膜,利用原子力显微镜、透射电镜、X射线衍射(XRD)及Raman光谱等测试分析手段对Co/BaTiO3纳米复合薄膜进行测试分析。结果表明:薄膜表面均匀、致密,具有原子尺度的光滑性;Co纳米晶粒呈单分散、均匀分散在沿C轴呈单取向生长的BaTiO3单晶基体中;随着掺杂Co含量的增高,BaTiO3的Raman峰的峰强随之增大。
The Co / BaTiO3 nanocomposite films were grown on the substrate of MgO (100) by pulsed laser vapor deposition (PLD). The properties of Co / BaTiO3 thin films were investigated by atomic force microscopy, transmission electron microscopy, XRD and Raman spectroscopy. Nanocomposite film for testing and analysis. The results show that the surface of the thin film is uniform and compact, and has the smoothness of the atomic scale. The Co nanocrystalline grains are monodispersed and uniformly dispersed in the monocrystalline BaTiO3 single crystal grown along the C axis. With the increase of doped Co content, The Raman peak intensity of BaTiO3 increases accordingly.
