近年来,通过在低温领域中的碳化氢等的气相分解,使金刚石那样的非平衡碳素的析出成为可能。但是,在低温低压下要使非平衡状态的金刚石析出,还需要在低温低压下形成与高温高压下构成金刚石的碳原子同样的结合状态。这样,就研究了在气相中生成具有SP~3杂 In recent years, the precipitation of non-equilibrium carbon such as diamond has been made possible by vapor phase decomposition of, for example, hydrocarbon in the field of low temperature. However, it is also necessary to form an unbalanced diamond at a low temperature and a low pressure, and it is necessary to form the same bonded state at a low temperature and a low pressure as the carbon atoms constituting the diamond under a high temperature and a high pressure. In this way, the study has been generated in the gas phase with SP ~ 3 miscellaneous
