ABSTRACT
We have used an atomic-force microscope tip to mechanically buckle single-walled carbon nanotubes. The resistance of the induced defects ranged from 10 to 100 kΩ and varied with the local Fermi level, as determined by scanned-gate microscopy. By forming two closely spaced defects on metallic nanotubes, we defined quantum dots less than 100 nm in length. These devices exhibited single-electron charging behavior at temperatures up to ∼165 K. © 2001 American Institute of Physics.

    We study the effect of wavelength on the laser-induced phase transformation in semiconductor quantum dots. In our earlier report [Yakovlev et al., Appl. Phys.

    Group IV semiconductors could have a completely new symmetry when the size is reduced to the range of several nanometers. For Si, the icosahedra are more stable than bulk-like quantum dots (QDs) for d < 5 nm (or N < 2400). At a given size, the icosahedral QDs are expected to be the most...
