  1. The major research interest covers a broad range of topics concerned with the fundamental properties of shallow - levels in semiconductors and with impurity related issues of importance to semiconductor physics and technology, e. g., single and multiple donors and acceptors, shallow excited states of deep - level impurities, defect interaction on the atomic scale such as impurity - pair or complex formation

    主要研究方向涵括半導體物理與技術方面有關雜質之重要領域,例如施者與受者雜質、淺與深雜質、雜質能階、雜質光譜、雜質與雜質或缺陷相互間之交互作用,以及復合雜質之形成與特性等。
  2. In order to combine biomass gasification technology, we have checked the fuel cell ' s impurity tolerance level. the results show that traces of h2s can damage the fuel cell. but co and cm almost have no influence on the performance of the fuel cell

    試驗結果表明, ch _ 4 、 co對燃料電池性能沒有太大的影響,而是作為燃料參加反應的,而微量的h _ 2s氣體即可對電極產生破壞性的作用,電解質中的碳酸根轉化為硫酸根,從而使電池失效。
  3. Deep impurity level

    深度雜質能級
