純鉈 的英文怎麼說
中文拼音 [chúntā]
純鉈
英文
pure thallium-
There are better performances in the films prepared by ba2ca2cu3ox target than by ba2cacu2ox target. the single - phase tl2ba2cacu2o8 hts thin film was obtained with a tc0 of 107k at the optimal tl2o partial pressure and thallination temperature 750. on excursion from the optimal conditions, there exist some impurities in the resultant films resulting in a reduction in tc0 and surface quality with change in the microstructure morphology
研究結果表明，採用成分為ba2ca2cu3ox的靶材制備的薄膜性能要優于成分為ba2cacu2ox的靶材；使用組成式為tl1 . 9ba2ca2cu3oy的鉈片做鉈源時，形成的tl2o分壓達到最佳值；在最佳tl2o分壓和最佳鉈化溫度750的條件下，制備出了純相完全c軸取向的tl2ba2cacu2o8高溫超導薄膜，其tc0高達107k ，膜面均勻平整光滑，呈圓片狀組織；偏離最佳制備工藝參數的條件下，制得的薄膜中都含有一定量的雜相，雜相的生成使得tc0值下降，薄膜表面質量下降，薄膜組織形貌發生變化。
