NOVEL ROOM TEMPERATURE ELECTROCHEMICAL DEPOSITION OF HIGH TEMPERATURE SUPERCONDUCTING FILMS

Abstract

The present review reports the innovative attempts made in the synthesis of a variety of high T c superconductor families in the form of thin films by electrochemical techniques. Summarizing the brief background of electrochemical deposition process, the growth mechanism of high T c superconducting films has been explained. The successful stories of room temperature electrochemical deposition of RE - Ba 2 Cu 3 O 7-δ, Bi – Sr – Ca – CuO , Tl – Ba – Ca – CuO , Hg – Ba – Ca – CuO and MgB2 superconductors in the form of thin films on silver substrates have been summarized. The room temperature electrochemical synthesis technique has helped to form a low-dimensional structure at the interface of Al/Tl-2223 hetero structure, which leads to a pathway for high T c and J c . The photoinduced effects of a variety of heterostructures formed with HTSC systems and CdSe semiconductor are also described.
