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。In this paper, the mechanism and practical effect of existing coordinated control schemes are analyzed in detail, the advantage and drawback of the different coordinated control methods in practice are indicated clearly. this paper describes a fact that it is difficult to obtain rapid load response and stable main parameters at the same time by using the recent methods, underlines that heat release is the vital parameter that should be carefully controlled
本篇在吸取了目前各種協調控制系統的優點的基礎上，提出了改進后的協調控制方案，主旨為以控制鍋爐的熱量釋放信號為核心，採用具有內在穩定特性的控制方案，充分加快機組的負荷響應速度，在機組所帶負荷已經接近當時的極限，及時限制輸出功率的增長，達到穩定機組的目的。
