Abstract

Thin film samples of the Bi-2212 and Tl-2212 high-Tc superconductors were prepared via metal-organic chemical vapor deposition with second generation precursors. The resulting epitaxial, c-axis oriented films were used for measurements of the in-plane resistivity versus temperature and room temperature thermoelectric power. The results for Bi-2212 thin films followed the established doping-dependent trends seen in other cuprate oxides and preliminary data for the Tl-2212 films show similar features as well. The results are compared to a generic normal state phase diagram for the cuprates.
