摘要：

In this paper, we report transport and transmission electron microscopy (TEM) measurements on Tl-based superconducting films prepared by two non-vacuum techniques: electrodeposition and spray pyrolysis. For electrodeposition, a conducting Ag layer was used on insulating substrates such as (LaAlO3) LAO to enable electroplating the Tl-oxide precursor films. The behaviour of the Ag layer after processing the precursor films has never been understood. We resolved this issue by performing TEM analysis of several processed electroplated Tl-oxide films. In this paper, we also report on the TEM analysis of MgO nanoparticle-incorporated spray pyrolysis films. Spray pyrolysis films were prepared with and without MgO nanoparticles. MgO nanoparticles were included in the spray pyrolysis films to improve the flux pinning and critical current densities of the Tl-1223 films.
