Abstract
The growth of Tl-2201 films on LaAlO3 single crystal substrates has been 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 the (0010) reflection had a FWHM of 0.27°. A Tc of 92K was achieved without post-annealing.
