  1. Based on the energy band characteristics of ordinary negative electron affinity emitter gaas, the design of lengthening the diffusion lengths of negative electron affinity emitter gaas was presented, and the special negative electron affinity emitter gaas was designed

    摘要根據通常負電子親和勢二次電子發射材料砷化鎵的能級特點,提出延長負電子親和勢二次電子發射材料砷化鎵的逸出深度的理論設計,設計出了特殊的負電子親和勢二次電子發射材料砷化鎵。
  2. According to the current problems such as low quantum efficiency. limited available sun energy spectrum range, and inefficient recovery, resulted from the practical using of photocatalysis, using the narrowband semiconductor cds ( eg = 2. 5ev ) to compound with tio2 seems to be an effective solution. since it will not only enlarge the region of the absorption with the proper narrow band of cds but also improve the photodegradation efficiency on account of the band overlap of the two, which makes the photo induced electron and holes separate more easily

    本文針對光催化技術應用中存在的tio _ 2光催化量子效率低,吸收利用太陽能光譜范圍有限,催化劑回收困難等問題,通過窄禁帶半導體cds ( e = 2 . 5ev )的復合,對納米tio _ 2進行了改性研究,一方面,由於cds的窄禁帶寬度可以擴展薄膜的光譜吸收范圍,另一方面,由於能帶的交疊,提高了光生電子和空穴的分離效率,從而提高了薄膜的光催化降解效率。
  3. We discuss the qcse of the impurity in the finite square qwws considering impurity position, and raise a point of the qcse under the influence of the masses mismatch and the aspect ratio of the quantum well wires. without considersion of the mismatch of the effective masses between the well and barrier, we obtain the conclusion as follows : ( l ) the first band energy of the electron is decreased under the electric field

    在前人工作的基礎上,我們在有效質量近似下討論了外加電場下有限深方形gaas ga _ ( 0 . 63 ) al _ ( 0 . 37 ) as量子阱線的雜質態和雜質的stark能移,並把我們的結果與前人的結果進行了比較。
