| Abstract: | In this paper, we report the detailed fabrication process of ultra-small SWNTs accommodated in the 1 nm-sized channels of microporous aluminaphosphate AlPO4-5 (AFI) single crystals. These nanotubes have been observed directly by transmission electron microscopy (Wang, 2000; Wang, 2001), and indirectly by X-ray diffuse scattering (Launois, 2000) as well as by micro-Raman measurements of the nanotube breathing mode (Sun, 1999a; Sun, 1999b). The data consistently indicate a nanotube diameter of 0.4 nm, probably at or close to the theoretical limit. The system of the mono-sized SWNTs stabilized in the zeolite channels brings the experimental results much closer to the real of theoretical predictability. It constitutes the best example of 1D quantum wires, and would have extremely interesting physical properties, which are not predicted in SWNTs of larger diameter. |
