  1. Gaas / algaas quantum well photodetectors ( qwips ) are new type devices and progressed rapidly in recent 20 years. qwips utilizing intersubband absorption between gallium arsenide ( gaas ) well and aluminum gallium arsenide ( alxga1 _ xas ) barriers were perfected. therefore, the ability to accurately control the band structure and hence the spectral response, as well as both established technology for growing and processing gaas optical devices and commercially available large area vlsi gaas ic ' s, makes gaas / algaas qwips attractive devices for use in very large focal plane arrays ( fpas ), especially available in the range of long wavelength 8 - 12 urn

  2. The result does not accord with the corresponding relation between the classical and the quantum. in quantum mechanics, because the particle has wave - corpuscle duality, the particle can tunnel the potential barrier which is higher than its energy

    這說明我們普遍認為的經典可積量子也可積的觀點在有些情況下並不適用，之所以會出現這個結果，與量子力學中粒子具有波粒二象性有很大關系，粒子的波動性使它能夠貫穿高度大於它自身能量的勢壘。
  3. 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。
  4. The transmission factor describes the gradual opening of a fission channel as the energy approaches the fission barrier.

    透射因子描述了當能量趨近於裂變勢壘時裂變逐漸地開放。
  5. Referring to the formation process of qd, it is accepted that there formed a groove around the dot during the formation process due to mass - transfer. when the dots were capped by a compound with larger band gap, there will appear a potential maximum due to larger confinement. the maximum will prevent the carriers from entering the dot, and the origin of the kink point is resulted from the prevention

    根據s - k模式量子點的形成過程，我們認為在點的形成過程中由於質量遷移會在點的周圍形成一個凹槽，加上覆蓋層后，由於大的量子限域效應該處將形成一個勢能極大值，該勢能極大值將阻礙載流子從勢壘層向量子點的注入，該過程是導致上述拐點出現的原因。
  6. In this paper, first, the study of the distribution of electromagnetic field, energy, power, reflection coefficient and transmission coefficient in waveguide with piecewise different dielectric constants are studied. then, the behavior of propagation of am signal and gauss pulse signal through the waveguide are simulated by magic code ， and the plots of electromagnetic field, energy, ponyting vector and their spectrums at different time and different position are obtained. and, the group velocity and energy velocity of wave packet through barrier are calculated

    從90年代開始， emig和martin 、 landauer等人研究了分段填充不同介質的波導中的電磁脈沖的傳播。在本論文中，作者首先推導出分段填充不同介質的波導中的電磁場分佈、能量、傳輸功率以及反射系數和傳輸系數的表達式，然後，採用magic程序模擬了這種波導結構中電磁波的傳播情況，得到了在不同時刻和不同位置處的電磁場分布圖、能量圖、坡印廷矢量圖以及它們的頻譜圖，並由模擬結果計算了波包穿越勢壘的群速和能量速度。
  7. It is showed the energy barrier is very high in transformation from h - bn to r - bn, but it is very low from r - bn to c - bn. in fact, defects and impurities in c - bn thin films might favorably drive the transformation from h - bn to c - bn. defects and impurities can reduce the energy barrier for the transformation from h - bn to r - bn

    研究發現:純的h - bn到r - bn的轉變需要克服一個很高的能量勢壘，而r - bn到c - bn的轉變只需要克服一個很低的能量勢壘; c - bn薄膜中存在的大量缺陷和雜質大大降低了從h - bn到r - bn轉變所需要的能量，促進了薄膜中立方相的形成。

  9. In the case of 8 interaction potential, because the range of action is very small, the influence that the energy levels are suffered by the tunneling effect is smaller than that of the nonzero distance interaction ; the system ca n ' t manifest the chaotic character. the conclusion shows that the wave - corpuscle duality and the tunneling effect can make t

    在占勢作用時，雖然也有勢壘隧穿ll . j影響，但是由於作用勢存在的范圍很小，量子系統的能級受到的影響t匕非零距離作用勢時小得多，所以不會出現goe的統計分佈。
