According to the raman selection rule and the pl measurement, it is reasonable to evaluate the quality of galnp / algalnp mqw by analyzing the relative intensity ratio of a1p - lo / to. ( 4 ) a new modified random element isodisplacement ( mrei ) model is set up to calculate the dependence between the long - wavelength optical phonon frequencies and the composition of iii - v - type ab1 - xcx mixed crystals. the second neighbor force constants are still assumed to be a linear variation with the composition, but the two first neighbor force constants can be evaluated to be a negative exponent variation with the composition, using the overlapped repulsive potential of the ion crystal combination
通過實驗我們找到了在這些結構參數上生產gainp algainpmqw的較理想的結果; ( 3 )首次用喇曼( raman )散射方法研究了常溫下的gainp algainp多量子阱結構,除了指認出喇曼光譜中各光學聲子模外,還結合樣品光致發光譜的測量結果,分析發現喇曼光譜中alp - lo to的相對強度比可以在一定程度上評定晶體gainp algainpmqw的生長質量; ( 4 )在修正的隨機元素等位移? mrei模型的基礎上建立了一個新模型,計算了ab _ ( 1 - x ) c _ x型?族半導體混晶的長波長光學聲子模頻率的組分變化關系。 -
Firstly, optical trigonometry measurement principle and wok principle of linear ccd are introduced, which are based on to design optical focusing and imagery system with he - ne laser instrument as illuminant. secondly, peripheral circuit of linear ccd is designed in theory and experiment. finally non - contact thickness measurement instrument is constructed, using ccd as photoelectric transformation element and microprocessor as the controller
本文首先介紹了光學三角法測量原理,並對線陣ccd的工作原理進行了研究,以此為基礎採用氦氖激光器為光源,設計了光學聚焦及成像系統,對線陣ccd外圍電路的設計進行了理論設計和實驗研究,最後設計了以ccd為光電轉換元件,以微處理器為控制核心的非接觸式厚度測量儀及其系統。
