Silicon nanowires have been grown by a plasma-assisted vapour-liquid-solid method using tin as the catalyst. Transmission electron microscopy in the [12[combining macron]10] zone axis shows that the diamond hexagonal (P6/mmc) crystal structure is present in several nanowires. This is the first unambiguous proof of the natural occurrence of this metastable phase to our knowledge.
采用等离子体辅助的汽液固法，以锡作为催化剂，生长了硅纳米线。在[12[combining macron]10]区轴的透射电子显微镜显示，在几根纳米线中存在着金刚石六方（P6/mmc）晶体结构。据我们所知，这是首次明确证明这种亚稳相的自然存在。
