采用溶液法中的金属有机物分解（MOD）法制备了（010）（或（100））取向的Bi2Sr2CaCu2O8 + x（Bi 2212）薄膜。实验中使用了平面的相邻（100）面（[001]方向的错切角φ= 5）的NdGaO3（NGO）衬底。当使用邻位衬底时，Bi 2212（020）（或（200））峰在XRD图中清晰地出现。由SEM图像可知，生长出了细长的板状的Bi 2212的晶粒。从晶格匹配的观点来看，该拉长的晶粒被认为是（010）（或（100））取向的Bi 2212晶粒。
We have prepared (010)(or (100)) oriented Bi 2 Sr 2 CaCu 2 O 8+ x (Bi2212) thin films by metal-organic decomposition (MOD) method which is one kind of solution method. The flat and vicinal (100) substrate (the miscut angle φ= 5 toward the direction [001]) of NdGaO 3 (NGO) was used. When using vicinal substrates, the Bi2212 (020)(or (200)) peak appeared clearly in the XRD patterns. From the SEM image, it was found that elongated plate-like crystal grains of Bi2212 were grown. From the viewpoint of lattice matching, this elongated crystal grain is considered to be (010)(or (100)) oriented Bi2212 crystal grains.
