Abstract: | High-T
c
superconducting thin films of Bi–Sr–Ca–Cu oxides were prepared by laser-induced plasma deposition of high-T
c
superconducting Bi2Sr2Ca1Cu2Ox and Bi2Sr2Ca2Cu3Ox targets in vacuum and a short post-annealing in air at 875°C. Thin films (thickness <500 nm) with a critical temperatureT
c
-onset of 95 K can be prepared on silicon substrate material with a SrTiO3 interface layer. The thin films were completely superconducting between 80 and 90 K. The stoichiometry transfer of superconducting target material by laser-induced plasma deposition was investigated. |
