Hall effect and magnetoresistance of thin films of carbon nanotubes
Abstract
We report Hall coefficient (R_H) and magnetoresistance (Δ ρ/ρ) measurements on thin films of aligned carbon nanotubes. RH is positive in the whole temperature range (1.7 - 300 K) showing the predominance of hole transport in the electronic conduction. The upper limit of the carrier concentration is 1.6*10^19 cm-3. The Δ ρ/ρ < 0 suggests a noncoherent transport between the nanotubes.
