例句與用法

1. Band overlap energy
   能帶重疊能量
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，由于cds的窄禁帶寬度可以擴展薄膜的光譜吸收范圍，另一方面，由于能帶的交疊，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。
