- 論文の詳細を見る
Nominal TlSr_2 (Er_<1-y>Sr_y) Cu_2O_x samples were prepared, and were investigated by powder X-ray diffraction analyses, and by resistivity and thermoelectric-power measurements. The samples with y=0.0-0.5 are nearly pure 1212-type phase TlSr_2 (Er_<1-y>Sr_y) Cu_2O_<7-δ>. The 1212 phase converts from semiconducting to superconducting at y=0.1-0.2, and exhibits the optimal superconducting behavior when y=0.4-0.5. In the range of 150-300K, the thermopower values of the 1212 phase are nearly temperature-independent. The hole concentration calculated from the thermopower data using the Hubbard model in high temperature limit with strong on-site Coulomb interaction is quantitatively consistent with the y/2 value.
