| 中文摘要 | Superconducting Tl(2)Ba(2)CaCu(2)O(8) thin films (Tl-2212) have been reproducibly fabricated on both sides of 2 inch LaAlO(3)(001) substrates by using a so-called two-step process. A simple and flexible horizontal arrangement inside the crucible during thallination has been proposed, to ensure a good convection of thallous oxide vapor around the film surface, and thus a high film quality on both sides. A good uniformity over the whole area of the films has been realized. The films are strongly textured, with the c-axis perpendicular to the substrate surface, and they show the fourfold symmetry of the tetragonal crystal structure. The full width at half maximum of the (002) peak for both films on the best sample is 0.43 degrees and 0.55 degrees respectively. The films exhibit flat terraces with particles and shallow holes, but free of microcracks. The superconducting critical temperatures fall in the range 105-108.5 K. The critical current densities are between 1.0 x 10(6) and 4.8 x 10(6) A cm(-2) at 77 K. The microwave surface resistances at the central area of the films are around 500 mu Omega at 77 K and 10 GHz. These films are suitable for microwave applications. |
