获得多功能单一过渡层是简化涂层导体多层结构的主要课题之一.采用化学溶液方法制备La掺杂CeO2过渡层,研究La掺杂量对CeO2薄膜表面形貌和双轴取向生长的影响.结果表明La掺杂量为10mol%的薄膜表面平整致密,且能保持锐利的双轴织构.通过多次涂敷工艺,获得具有120nm厚的Ce0.9La0.1O2过渡层.采用脉冲激光沉积方法在Ce0.9La0.1O2/NiW结构模板层上沉积了YBCO超导薄膜,其起始临界转变温度达到90.5K.这表明采用化学溶液方法制备Ce0.9La0.1O2薄膜是一种有前景的简化涂层导体多层结构的方法.
Obtaining multifunctional single transition layer is one of the main topics to simplify the multi-layer structure of coated conductor.La-doped CeO2 transition layer was prepared by chemical solution method, and the effect of La doping amount on the surface morphology and biaxial orientation growth of CeO2 thin film The results show that the film with 10mol% La doping content is smooth and compact, and can maintain the sharp biaxial texture.A multilayer Ce0.9La0.1O2 transition layer with 120nm thickness was obtained by multiple coating process.A pulsed laser deposition Methods YBCO thin films were deposited on the Ce0.9La0.1O2 / NiW template with an initial critical transition temperature of 90.5 K. This shows that the preparation of Ce0.9La0.1O2 thin films by chemical solution is a promising method to simplify Coating conductor multilayer structure method.
