【摘要】 根据BiSrCaCuO高T_c超导氧化物具有层状结构的特点,我们采用背面防护机械解理的简易方法,制备出具有较大面积薄区(n+μm)的TEM样品。现已观察到BiSrCaCuO薄膜样品中存在位错网络和丰富的条纹等有兴趣的结果。更多还原

【Abstract】 A technique of back-protection mechanic cleaving has been developed for preparing TEM specimens of BISrCaCuO superconducting thin fihns. Some interesting features such as dislocation network and the dissociation of lislocation at the node are observed.更多还原
