Abstract
The growth of Tl-2201 films on LaAlO3 single crystal substrates has be en investigated. The synthesis involved precursor films made by laser ablation that were treated with Tl2O(g) in near-equilibrium conditions . By optimising the method of preparation, we obtained films that were highly smooth, c-axis oriented and epitaxial. The rocking curve of th e (00<(10)under bar>) reflection had a FWHM of 0.27 degrees. A T-c of 92K was achieved without post-annealing.
