The recent developments on the research for the TiO2 capacitor-varistor ceramics were reviewed in this paper, which contain donor impurity, acceptor impurity and sintering improver, and the evolution of it was forecast at the same time. 本文综述了TiO2电容-压敏陶瓷性能以及施主杂质、受主杂质、烧结助剂的研究现状,并对其进行了展望。
Therefore, the correctness of understanding that the gold acceptor level and the doner level in silicon essentially originate from the same gold impurity is then supported forcefully, from based model in this work. 因而,根据本工作所依据的模型,则是有力地支持了硅中金受主能级与施主能级本届同一金杂质的两个能级的认识的正确性。
The research of open-tube double acceptor mixing technique is carried out to overcome the disadvantage of manufacturing high-voltage thyristor p type impurity diffusion technique. 针对制造高压晶闸管p型杂质扩散工艺的不足,进行了开管式受主双质掺杂技术的研究。
