Abstract
Superconducting YBaCuO (1-2-3) thin films have been deposited on GaAs by laser ablation, in the presence of an oxygen plasma, at a substrate temperature of 600 °C. The (100) GaAs had a thin (100 Å) Al0.3Ga0.7As cap layer, in order to prevent decomposition of the GaAs. The as-deposited YBaCuO film had a Tc (onset) of 80 K and a Tc (zero) of 20 K. Transmission electron microscopy studies showed the presence of voids in the GaAs, ∼1000 Å in length, and extending 500 Å into the GaAs.Keywords
