Furthermore, the growth and the study of self - organized quantum dots structures become more and more important recently, and the application of self - organization technique become wider and wider in this thesis, we address the theory of film growth and the growth technique firstly more, the ways and characteristics of surface detection are prescribed we mainly report the growth process, results and discuss of self - organized quantum dots structures in the a12o3 substrates by s - k mode using ecr - mocvd, in the espd - u device the growth art of ain epilayer which is the preliminary foundation of self - organized gan / ain quantum dots structures, including the substrate cleaning, nitridation, the growth of buffer and the growth of gan and ain epilayer, is discussed we deliberately compare the test result of rheed xrd and afm and achieved the optimalized condition of ain at last we have successfully realized the growth of ain which is much smooth and better crystal quality moreover, we grow the self - organized gan / ain quantum dots structure in s - k mode because the limits of the heater temperature, we can not grow the atom - smooth epilayer of ain until now so we could not grow better quantum dots which have small diameter and big density but the self - organized quantum dots structures with better quality will be realized successfully if the substrate temperature is increased the thesis study belong to my tutor subject of national nature science foundation ( 69976008 )
本論文主要論述了在espd - u裝置上，採用電子迴旋共振等離子體增強mocvd （ ecr - pamocvd ）方法，在藍寶石襯底上通過s - k模式自組裝生長gan aln量子點結構的生長工藝、結果及討論。而重點分析了自組裝生長量子點之前的aln外延層生長工藝，包括襯底清洗、氮化、緩沖層的生長和gan 、 aln外延層的生長；通過高能電子衍射、 x射線衍射和原子力顯微鏡測試，並且對這些測試結果進行了詳細的比較研究，得出了較優化的工藝條件，生長出了晶質較好、表面較平整的aln外延層；進而採用s - k模式自組裝生長了gan aln量子點結構。由於實驗裝置加熱爐溫度的限制，我們沒有能夠生長出原子級平滑的aln外延層表面，因而沒能夠生長出密度比較大和直徑比較小的量子點。It ' s pointed out that, under the condition of vim refining, the amount of oxide inclusions residue in molten steel increases with the increased loss of deoxidizing elements, and the key of melting extra - low oxygen steel is to avoid the thermal decomposition of lining material ; the size of deoxidizing products increases with the increased degree of supersaturation of deoxidizing elements ; larger inclusions granules found in extra - low oxygen steel come mainly from lining material
結果表明，在真空感應熔煉條件下，殘留在鋼中的氧化物夾雜數量隨脫氧元素鋁燒損量增加而增加，熔煉超低氧鋼的關鍵是避免爐襯熱分解；脫氧產物尺寸隨脫氧元素過飽和度增加而增加；超低氧鋼的大顆粒夾雜主要來自爐襯材料。
