摘要：
Monodispersed single-walled carbon nanotubes are formed in the one-dimensional channels of AlPO(4)-5 crystals by pyrolysis of hydrocarbons. DC current-voltage properties were measured under magnetic field at various temperatures. The nanotubes demonstrate one-dimensional semiconducting properties. Its energy gap is determined from the experimental data to be 52 meV. A negative magnetoconductance was observed and explained as a result of bad-gap increase induced by the magnetic field.
