Paper Abstract

Quantum wire is one of the central subjects of nano-electronics. Quantum wire shows unusual electronic and optical properties attributed to the following effects: quantum confinement effect, surface effects, and quantum tunneling effect. Many different kinds of techniques have been developed for researchers to produce quantum wires, such as laser ablation technique, electrochemical processing, chemical vapor deposition technique, etc. However, controlling the sample size and orientation distribution is a big challenge in these fabrication methods. One promising technique to prepare monosized well-aligned quantum wires is using template technique, i.e., deposition of guests into porous matrices. In this paper, several template synthesis processes for preparations of carbon nanotubes were investigated. The carbon nanotubes produced by template technique have narrow size distributions and involve fragments of highly ordered shapes which are due to the limitation of matrix size and channel direction. Because of the restricted dimension of the matrix, the system shows peculiar properties such as polarization in spectra, strong quantum effects, and faster optical response. These may be used in electric transport, optic switches, nonlinear optics and lasers.
