Popis: | The vapor-liquid-solid (VLS) growth technique is a combination of pulsed laser deposition (PLD) method and liquid phase epitaxy (LPE) and is expected to fabricate structures with high crystallinity at a high deposition rate. To utilize superconducting coated conductors (CCs) for applications such as superconducting magnets, it is indispensable to decrease the fabrication cost of CCs. Therefore, we have devised a method to achieve a deposition rate of 26.0 nm/s by changing the partial pressure of O2 during deposition. Furthermore, an enhanced crystallinity was maintained by using the VLS growth technique, with a thickness of up to 10 μm, and we achieved a critical current I c of 625 A/cm-w. |
