| 摘 要： | 氢在金刚石中往往以一定的化学态形式存在,不同类型的金刚石中氢会以不同的电荷状态进行迁移与扩散,也可以与其他杂质元素N、B、P等作用,形成(N,H)、(B,H)、(P,H)对;为高温高压合成金刚石的物质体系中引入氢,有利于提高高温高压合成金刚石的产量、粒度及品级,也将为模拟天然金刚石的形成与探讨地球深部的动力学过程提供科学线索。

| Abstract: | Hydrogen is an essential impurity existed as some chemical states in diamond.Theoretically,hydrogen could be migrated and diffused in one of the three charge states,H~ ,H~0 and H~-in various kinds of diamond.Moreover it may form complexes(N,H),(B,H),(P,H) with other impurities(N,B,P),native defects or with other hydrogen atoms.Adding hydrogen into the material system for synthezing diamond under HPHT will be helpful for improving the production,grain size and grade of the synthezed diamond.It also will help to simulate the formation of natural diamond and to discuss the geodynamic course in depth of the earth. |
