Gan是直接躍遷的寬帶隙材料，具有禁帶寬度大（ 3 . 4ev ，遠大於si的1 . 12ev ，也大於sic的3 . 0ev ） ，電子漂移飽和速度高，介電常數小，導熱性能好等特點，在光電子器件和電子器件領域有著廣泛的應用前景。Pure cdte films have high electrical resistivity and are slightly p - type, due to the formation of cd vacancies in the cdte lattice acting as acceptor centers. the sheet resistivity of films are about 1010 ? / ?. the sheet hole concentration is 105 - 6 / cm2 and the hall mobility is about hundreds cm2 / v. s. the structural and electrical properties of cdte films doped te are markedly different from pure cdte films
，面載流子濃度約105 - 6 / cm2 ，載流子遷移率為幾百cm2 / v . s ；摻雜te元素后，薄膜衍射峰強增大，薄膜結構上出現了第二種相成分?六方結構的te ，由衍射峰強判斷該相比例較小，同時cdte薄膜的衍射峰向低角度偏移，晶格< wp = 5 >常數增大。The ratio of water vapor transfer contrasting with admixture transfer reveals that usually water vapor transfer can not be neglected
氣態水遷移量占混合遷移量的比例數值表明，通常非飽和土水分遷移中氣態水遷移是不可忽視的。Professor guo dajun has summarized in his work [ 7 ]. such several important tasks and theirs application of nonlinear functional analysis as typical nonlinear operators, hammerstein integral operations, ordinarily and partially differential equations. the cone theory, the positive solutions of nonlinear operator equations, the number and the branch of solutions, and so on. reference [ 1 ] includes all levels of results of the domain such as nonlinear functional analysis
郭大鈞先生在專著[ 7 ]中對非線性泛函分析的幾個重要課題及其應用，諸如典型的非線性運算元、 hammerstein積分方程、常、偏微分方程、遷移方程、錐理論及非線性運算元方程的正解、非線性運算元拓撲度和不動點定理以及固有值、解的個數與分支，都做了系統的概括和總結But for the moment, the examples discovered in gabon remain unique windows on possible changes in fundamental physical constants and on how buried nuclear waste migrates over time
不過現階段而言，要研究基礎物理常數可能的變化以及埋藏的核廢料如何隨時間遷移，加彭的例子仍是我們唯一的窗口。Due to the change in lattice constant and the distortion of energy band, strained si exhibits great mobility enhancement compared with the conventional si material, and it is the critical reason for the wide application of strained si mosfets
由於晶格常數的改變，應變硅中載流子的遷移率高於普通硅材料，這是應變硅mosfet性能提高的根本原因。Here are some routines that will help you easily migrate some frequently - used functionality in other database products
