摘要：

Methods of making electrical contact to high-T(c) superconductors with conductive polymers are described. In addition, three- and four-point resistance measurements are acquired on samples of YBa2Cu3O7-delta, GdBa2Cu3O7-delta, and Pb0.3Bi1.7Sr1.6Ca2.4Cu3O10 using poly(3-hexylthiophene) contacts in order to determine the temperature dependence of the conductive polymer/superconductor contact resistance. Although the polymer/superconductor contact resistance displays activated behavior above T(c) and increases as the temperature is lowered, below T(c) there is a precipitous decrease in the resistance at that interface. Similar measurements completed on systems where the superconducting components are substituted by normal metals do not show any signs of such contact resistance decreases. Possible reasons for the decrease in the polymer/superconductor interface resistance at T(c) are discussed.
