Abstract
We have studied magnetic field and temperature dependence of electron transport in chemical vapor deposition synthesized highly resistive multiwalled carbon nanotubes. The analysis of the weak-localization magnetoresistance according to electron-electron interaction theories leads to very small mean free paths, l<10 nm. At lowest temperatures the sheet resistance is near RK=h/e exp 2. Both of these observations suggest that our samples are close to the strong-localization limit.
