种子层 meaning in Chinese
seed layer
Examples
- For the preparation of coated conductors , one of the most important issues is the growth of seed layer ( the first buffer layer ) , which provide a continuous , smooth , and chemically inert surface for the growth of the ybco film while transferring the biaxial texture from the substrate to the htsc layer
在二代涂层导体中,第一层过渡层(也称为种子层)起着顺延织构和阻挡基带与超导层之间互扩散的重要作用,因此,种子层是涂层导体制备的关键。 - Water steam was used as oxidant , and the optimum water steam partial pressure is between 1 10 - 4 and 5 . 5 10 - 4 pa . under the optimum growth parameters , a ceo _ 2 seed layer with highly textured degree was successfully prepared . beside the one step process was experimented in this dissertation , the two step process was proposed and studied to further improve the quality of ceo _ 2 seed layer . in the two step process , about 15 nm thick of ce metal layer was deposited on metallic substrate at the first step , then water steam was introduced in the chamber , and the ceo _ 2 thin films were subsequently deposited with reactive sputtering in the
总结出沉积ceo _ 2薄膜的优化工艺条件,当沉积温度为720 - 850 、水蒸汽分压介于1 10 - 4 - 5 . 5 10 - 4pa之间、退火时间40min时,获得了织构程度良好的ceo _ 2种子层薄膜; 3 .由于一步法制备ceo _ 2种子层中水分压范围狭窄,工艺条件难以控制,并且退火延长了薄膜的制备时间,因此,本论文又采用了两步生长法沉积ceo _ 2种子层,即:先在ni - w基带上沉积一层约15nm的金属ce薄膜,再通入氧化气氛(水蒸汽) ,继续进行薄膜沉积。
