Bi2Sr2CaCu2O8 (Bi2212) is one of the most promising high temperature superconductors for use in power applications such as generators and fusion reactors. However, the present technology used for the manufacture of long wires involves a large proportion of silver, which makes the cost of such wires prohibitive for large scale exploitation. We explore alternative ways of making Bi2212 wires in the form of multilayer thin film stacks on top of long, flexible non-noble metal substrates. For this purpose, we recently developed a chemical solution deposition technique, which could be used for cheap deposition of Bi2212 films on long substrates in a reel-to-reel setup. Unfortunately, the solvent presents safety issues. It is therefore important to develop alternative routes making use of a harmless solvent, ideally a water based solution.

The aim of this project is to test green chemistry approaches for the manufacture of Bi2212 thin films. This work will involve a thorough characterization of the transformation from the homogeneous solution to the final Bi2212 film, extended characterization of the microstructure and physical properties of the films and an analysis of the relationships between processing parameters and film performance.   

 

During this project you are going to:

-Develop a green-chemistry process and use it to synthesize Bi2Sr2CaCu2O8 high temperature superconducting films on various substrates.

-Analyze the decomposition process of your solution and the reaction leading to the formation of the superconducting layer.

-Conduct microstructural characterization of your samples by means of X-ray diffraction, optical and electron microscopy.

-Perform magnetization measurements at cryogenic temperatures under magnetic field to evaluate the superconducting performance of your samples.

-Analyze your experimental results using state of the art theoretical models.

 

Learning objectives:

At the end of this project you will be able to:

-Use various experimental characterization tools (X-ray diffraction, thermal analysis, infrared spectroscopy, electron microscopy, low temperature magnetization measurements) and explain their basic principles as well as limitations.

-Critically evaluate your results.

-Draw links between microstructure and performance.

-Perform an efficient literature search and compare your own results to published data.

-Present your results to a scientific audience under conditions equivalent to an international conference.

-Write the draft of a scientific publication.
