Room-temperature electrochemical synthesis of sequentially layered superconducting Bi-Sr-Ca-Cu-O films

A room-temperature electrochemical synthesis of Bi-Sr-Ca-Cu-O films on to Ag substrates has been successfully carried out using a layer-by-layer electrodeposition technique. The various preparative parameters, such as deposition potential and current density, have been studied and optimized. The ele...

Zusammenfassung:	A room-temperature electrochemical synthesis of Bi-Sr-Ca-Cu-O films on to Ag substrates has been successfully carried out using a layer-by-layer electrodeposition technique. The various preparative parameters, such as deposition potential and current density, have been studied and optimized. The electrochemical oxidation of these films in alkaline solution (1N KOH) has been used for preparing the Bi-Sr-Ca-Cu-O superconducting phase. The oxidized film showed superconductivity below 110 K.
