表面法线与（001）面有一定倾角的单晶SrTiO3基片上，用磁控溅射的方法生长TlBaCaCuO超导薄膜，转变温度约为100K。利用扫描电镜来对不同角度下生长的TlBaCaCuO薄膜的表面形貌进行观察分析，并通过X光谱对其晶格结构进行研究，我们发现它们的表面形貌在不同角度时其平滑程度不同，在倾角较小时，其结构同在无倾角基片上生长的薄膜结构基本一样，都是沿SrTiO3基片C轴外延生长成单晶织构，其（001）方向与SrTiO3基片的（001）方向一致。而当倾用较大时，薄膜已无法沿SrTiO3基片C轴外延生长成单晶织构。结构上的不同，使得它们在脉冲激光照射其上时产生的激光感生电压信号的峰值和形状都有很大的不同，并且信号的形状和大小与我们正在研究的YBCO薄膜激光感生电压信号也有很大的不同。
Surface normal and (001) plane with a certain tilt angle of the substrate SrTiO3, magnetron sputtering growth TlBaCaCuO superconducting thin film, the transition temperature of about 100K. Scanning electron microscopy (SEM) was used to observe the surface morphology of TlBaCaCuO films grown at different angles. The crystal structure of TlBaCaCuO films was studied by X-ray spectroscopy. We found that the surface morphology of TlBaCaCuO films is different at different angles, The structure is similar to that of the films grown on non-tilted substrates. Both of them are epitaxially grown along the C axis of the SrTiO3 into single-crystal texture. The (001) direction coincides with the (001) direction of the SrTiO3 substrate. When the pouring is large, the film can not epitaxial growth along the C axis of SrTiO3 substrate into single crystal texture. The structural differences make the peak and shape of the laser-induced voltage signal produced by pulsed laser irradiation very different from each other, and the shape and size of the signal are similar to those of the YBCO film laser induced voltage signal There are also big differences.
