本文利用透射电子显微术研究了外延生长的多铁BiFeO_3/NdGaO_3(110) O薄膜中的界面重构现象。高分辨HAADF-STEM像表明:衬底的截止层为GaO_2原子层;在BiFeO_3/NdGaO_3界面处,Nd元素部分取代了BiFeO_3的Bi元素,从而在平行于界面的第一原子层形成了BiO-NdO交替排列的界面重构形态。利用寻峰拟合方法对高分辨HAADF-STEM像的分析表明,这种界面重构的发生可以部分释放衬底施加的压应变。本研究提出了多铁材料BiFeO_3薄膜中一种新的应变释放途径。 |

The interface reconstruction in epitaxial BiFeO_3/NdGaO_3 (110) O films was analyzed by transmission electron microscopy. The atomically resolved HAADF-STEM images demonstrated that the termination of the substrate was GaO_2 layer. At the first layer of interface,the element of Nd in substrate partially substituted for the Bi element in BFO film,leading to the formation of interface reconstruction,arranged alternatively in the form of BiO column and NdO column. The analyses of HAADF-STEM images with peak finding revealed that the interface reconstruction could partially release the compressive strain from substrates. These results have proposed an alternative way to release strain in multiferroic BFO films. |
