Abstract	0.4 nm-sized single-walled carbon nanotubes (SWNTs) were produced by means of pyrolysing hydrocarbon molecules in 1 nm-sized channels of AlPO -5 (AFI) single crystals. These small SWNTs are highly aligned and uniform in size. They behave as a good polarizer, having strong absorption for the light polarized parallel to the tube direction, and nearly transparent for the light polarized in perpendicular direction. The absorption bands are assigned to the dipole transitions between the van-Hove singularities. Resonant Raman scattering measurement confirmed these van-Hove singularity structures. Investigation of the magnetic and transport properties of these SWNTs revealed that at temperatures below 20 K, the 0.4 nm tubes exhibit superconducting behavior manifest as an anisotropic Meissner effect, with a superconducting gap and fluctuation supercurrent.
