Abstract
The fabrication of pure a-axis oriented Tl2Ba2Ca1Cu2O8 (Tl-2212) superconducting thin films, prepared ex-situ. by a combined approach of metal-organic chemical vapor deposition (MOCVD) and thallium vapor diffusion, is reported. The unusual orientation has been obtained by depositing the superconducting films on LaAlO3 (100) buffer layers grown on SrTiO3 (100) substrates. The micro-structural and superconducting properties of a-axis oriented films have been investigated and compared with those of the c-axis oriented samples simultaneously deposited.File in questo prodotto:
