Abstract High temperature, high pressure conditions were used to insert liquid bismuth in 4–6 nm diameter amorphous silica nanotubes. A combination of transmission electron microscopy and neutron powder diffraction indicate that the final composite consists in 5–6 nm semi-conducting Bi nanowires confined in insulating mesoporous α-quartz. Such a nanostructured material could be of considerable interest for thermoelectric applications.

介孔α-石英/铋纳米线复合材料的高压、高温合成

摘要 在高温、高压条件下将液态铋嵌入直径为 4-6 nm 的无定形二氧化硅纳米管中。透射电子显微镜和中子粉末衍射的组合表明，最终的复合材料由限制在绝缘介孔 α-石英中的 5-6 nm 半导体铋纳米线组成。这种纳米结构材料对于热电应用可能具有相当大的意义。
