摘要:
Interfacial interaction between Bi2Sr2CaCu2O8+&dgr;highTcsuperconductor and indium metal has been investigated using photoemission measurements. The results indicate that a sharp interface is possible and the interfacial interaction is restricted to a region of ∼5 A˚ thickness. In this region, there is a substantial CuO and SrO bond breaking.
