A comparative study on liquid phase epitaxy initial stage of REBCO on MgO substrate

The Orientation Transition and Control of REBaCu3Oy Films Grown by Liquid Phase Epitaxy

“…Additionally, it has been reported that the REBCO thin film possess superior thermal stability . Since it is convenient to grow sizable LPE films with excellent crystallinity repeatedly and reliably, the thin films can act as seed materials to induce well oriented REBCO and mixed REBCO single crystals, films and single-domain bulks with large size and high performance. − This may bring about large-scale productions and commercial applications of reproducible REBCO materials. Moreover, the comprehensive review on the supersaturation control interprets the formation mechanism of various solution states and the comprehensive correlation between supersaturation and growth rates of a - and c -grains.…”

Peritectic melting of thin films, superheating and applications in growth of REBCO superconductors

“…This is of great significance in technological applications in various fields, such as HTS device, persistent current switch (PCS) device and coated conductor. So far, using YBCO/MgO thin-film-seed, the LPE thick-film growth have been successfully achieved in various oxide materials (see Table 1) [24][25][26][27][28]. Secondly, not only valid for the LPE growth, the principle of YSNG can presumably be utilized for other seed-required HTS processes, e.g., the single crystal growth, the bulk growth and the coated conductor process.…”

“…4, which illustrate an example of the observation of melting process of the YBCO thin film grown on the MgO substrate. Plenty of small black dots on the YBCO 1050°C [28] thin film can be observed from Fig. 4(a) at room temperature, which were either YBCO crystal defects or impurities.…”
