Zhao, X. Y., Wei C. M., Yang L., & Chou M. Y. (2004).  Quantum confinement and electronic properties of silicon nanowires. Physical Review Letters. 92, 4., Jun, Number 23 AbstractWebsite

We investigate the structural, electronic, and optical properties of hydrogen-passivated silicon nanowires along [110] and [111] directions with diameter d up to 4.2 nm from first principles. The size and orientation dependence of the band gap is investigated and the local-density gap is corrected with the GW approximation. Quantum confinement becomes significant for d<2.2 nm, where the dielectric function exhibits strong anisotropy and new low-energy absorption peaks start to appear in the imaginary part of the dielectric function for polarization along the wire axis.

Zhao, X., Liu Y., Inoue S., Suzuki T., Jones R. O., & Ando Y. (2004).  Smallest carbon nanotube Is 3 angstrom in diameter. Physical Review Letters. 92, 3., Mar, Number 12 AbstractWebsite

Previous energetic considerations have led to the belief that carbon nanotubes (CNTs) of 4 Angstrom in diameter are the smallest stable CNTs. Using high-resolution transmission electron microscopy, we find that a stable 3 Angstrom CNT can be grown inside a multiwalled carbon nanotube. Density functional calculations indicate that the 3 Angstrom CNT is the armchair CNT(2,2) with a radial breathing mode at 787 cm(-1). Each end can be capped by half of a C(12) cage (hexagonal prism) containing tetragons.
