Description
The tunneling I-V characteristic curves have been studied for a ceramic sample of Tl2Ba2Ca2Cu3O10+δ using a scanning tunneling microscope. We have found two kinds of curves which are interpreted as due to the tunneling in superconductor--insulator--normal-metal and superconductor-insulator-superconductor junctions. Although the Tc of the intervenient superconducting regions are unknown, values of 2Δ/kBTc are around the BCS value 3.5 using the Tc obtained by resistance measurements
