exciton migration 中文意思是什麼

exciton migration 解釋
激子徙動
  • exciton : n. 【物理學】激子。adj. -ic ,-ics n. 〈用作單數〉【物理學】激子學。
  • migration : n. 1. 移住，遷移；移動；徙動。2. （鳥）移棲，遷徙；（魚）洄遊；（植物）侵移。3. 移住者群，移棲群。4. 【化、物】原子移動；電離子的移動。
  1. On the basis of one - electron hartree - fock approximation, the extended - ion method and ab initio method have been used to investigate the f center migration between f ~ - layers, br ~ - layers and from f ~ - layer to br ~ - layer. we have calculated the energy barrier of these three f center migrationes and energy of f center, exciton energy. the results of f center and exciton are in good agreement with the experimential data

    本文是在單電子hartree - fock近似的基礎上採用擴展離子方法和全電子從頭計算方法，研究了bafbr ： eu ~ （ 2 + ）晶格中的f ~ -離子層間的f心遷移， br ~ -層的f心遷移和f ~ -離子與br ~ -離子層間f心遷移過程中的能量勢壘和f心基態、激發態以及激子能量，對于f心和激子的研究結果與實驗符合的很好。
  2. Psl occurs while eu2 + transferring from 4fb5d7 to 4f7 or when exciton transferring to 4f7 defectively. we give the physical imagination about several possible migration paths of f center, which offer more full and accurate theory basis to comprehend the cause of psl phenomenon in bafbr : eu2 + crystal

    我們詳細給出了在bafbr ： eu ~ （ 2 + ）晶格中不同位置f心可能移動路徑的物理圖景，從而為更好的理解bafbr ： eu ~ （ 2 + ）晶格中psl現象的產生提供了更加翔實的理論依據。
