摘要：

The electronic properties of aligned carbon nanotube films have been investigated by conduction electron spin resonance (CESR) and transport measurements. Hall effect and CESR reveal that the nanotubes behave like a semimetal with 10(19) carriers/cm(3) at room temperature. The intrinsic resistivity is an order of magnitude lower than the de resistivity of the films. Strong deviations in the physical characteristics suggest a charge-carrier localisation below 40 K. Low level of doping with Potassium strongly modifies the electronic properties of the nanotubes.
