Abstract:

A novel drop-on-demand IJP deposition methodology for the preparation of thick YBCO is presented. The advantage relies on the high throughput advantages of the used precursors in combination with Transient Liquid Assisted Growth (TLAG) of CSD layers, with ultrafast growth rates (>1000 nm/s). The use of different additives, deposition and evaporation strategies, together with the rheological properties of the solution, thermogravimetric analysis and the identification of stress-relief mechanisms, have been thoroughly analysed using advanced in-situ characterization techniques to obtain homogenous depositions and defect-free pyrolized films with high thickness. Inkjet Printing allows the fabrication of good quality 1µm YBCO films in one single deposition, with high throughput in a reproducible way, reducing the cost of a scalable industrial process, making it interesting for the market.
