In this paper x - ray diffraction dynamical theory and kinematicai theory fbr low - dimension semi - conductor hetero - epitaxy materials are analyzed particularly and are applied to analyze the structure of 1ow - dimension semi - conductor <中文摘要> =摘要本文詳細(xì)分析了x射線衍射的動力學(xué)理論和運(yùn)動學(xué)理論,并將其應(yīng)用到低維半導(dǎo)體材料的結(jié)構(gòu)分析。
The experimental results revealed that except for a much - complicated material structure in which the kinematical theory ' s sensitivity to structural parameters become comparatively lower than the dynamical theory , applying kinematical theory to a common structure material by introducing the prior amend can draw to a fairly consistent conclusion with the experimental results . besides , the clear physical meaning of kinematical is critical aid in explain the simulation results and in later parameters adjustment in material growth 我們的實(shí)驗(yàn)結(jié)果證明:對于大多數(shù)結(jié)構(gòu)比較簡單的材料,在引入適當(dāng)?shù)男拚呗院螅\(yùn)動學(xué)理論能得到與測量曲線吻合更好的擬合結(jié)果;當(dāng)材料結(jié)構(gòu)過于復(fù)雜時(shí),運(yùn)動學(xué)理論對于材料參數(shù)的靈敏度會低于動力學(xué)理論;此外,運(yùn)動學(xué)理論的應(yīng)用不僅可以使分析過程中的參數(shù)調(diào)整有明確的方向性,而且其物理思想對于分析結(jié)果的解釋以及材料生長過程的指導(dǎo)都具有重要意義。
