杂质光谱 meaning in English

impurity spectrum

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导体物理与技术方面有关杂质之重要领域，例如施者与受者杂质、浅与深杂质、杂质能阶、杂质光谱、杂质与杂质或缺陷相互间之交互作用，以及复合杂质之形成与特性等。
