摘要：
We have investigated temperature sigma(T) and magnetic field sigma(B) dependences of the conductivity sigma of multiwalled carbon nanotubes (MWNTs) with different average outer diameter (d) over bar. From the experimental data we have separated the quantum corrections to sigma(T) and sigma(B). We have discovered that only quantum corrections for interaction electrons (QCIE) to sigma(B) take place. It is associated to the absence of the bulk formations of amorphous carbon in produced MWNTs. From the data of QCIE we have estimated the constant of electron-electron interaction lambda which is negative (attraction between electrons) and gradually falling with decrease in MWNTs (d) over bar. Influence of defectiveness and structure of MWNTs on electrophysical properties is discussed. (C) 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
