An evaluation of thermal conductivity of high-temperature superconductors

Neeraj Kumar Mishra, Priyanka Vaidya

This paper deals with the transport properties of high temperature superconductors. The transport properties are temperature dependence of thermal conductivity of high Tc superconductor. We have taken two different high Tc superconductors in our studies namely La2-nSrnCuO4 and YBa2Cu3O7-δ. These superconductors bear transition temperature from 38K to 110K. Transport properties basically concerns with the movement of the classic carriers in the solid. In the case of superconductors the carriers are super electrons which move in the vicinity of a different excitation of the solid created by the impurity which has been dropped in the system. It was believed that as in the case of noble metal or low Tc superconductors (Tc from 1K to 24K) phonons has dominant role in different transport properties. From the investigation this has been ruled out. Phonons does play role in the high Tc superconductor only above Tc. The studies of thermal conductivities of high Tc superconductors indicate that the phonons contributions are larger near Tc and smaller far away.
