| 中文摘要 | Temperature dependences of the electrical resistivity of samples of carbon nanoparticles obtained from nanodiamonds by annealing at 1800, 1900, and 2140 K were studied. The magnetoresistance of these samples was measured at 4.5 K. Data on the positive magnetoresistance obtained in fields above 3 T were used to estimate the mean free path l of carriers at liquid-helium temperature, l similar to 12 Angstrom for a sample annealed at 1800 K, l similar to 80 Angstrom for a sample annealed at 1900 K, and l similar to 18 Angstrom for the case of annealing at 2140 K. The samples annealed at 1800 and 2140 K exhibit a negative magnetoresistance in fields below 2 T. The carrier concentrations n in the samples annealed at 1800 and 2140 K were estimated as n similar to 8 x 10(21) and 3 x 10(21) cm(-3), respectively. (C) 2002 MAIK "Nauka / Interperiodica". |
