摘要
新型超硬材料β-C3N4自从理论预言其硬度有可能超过金刚石以及优异的性能以后成为各国科学家研究的热点.目前在理论计算和实验合成方面都已取得了一定的进展.本文介绍了氮化碳薄膜的合成方法、表征手段及薄膜质量,分析了氮化碳晶体制备中存在的一些困难,并对今后的研究重点作了展望.
A new kind of superhard material β-C3N4 has become the hot research point because of its hardness maybe over diamond and other possible excellent properties since it had been predicted in theory. Progress has been made in present study. The sythesis methods, characterization and qualities of carbon nitride films have been reviewed in this paper. Finally, the existent difficulties in the process of sythesis carbon nitride have been analyzed and the future developments are prospected.
