- Abstract
Electrical conductivity σ( T) of the paper consisting of multiwalled carbon nanotubes (MWCNTs) is studied in the temperature range 4.2-295 K, and its magnetoresistivity ρ( B) at various temperatures in magnetic fields up to 9 T is analyzed. The temperature dependence of the paper electrical conductivity σ( T) exhibits two-dimensional quantum corrections to the conductivity below 10 K. The dependences of negative magnetoresistivity ρ( B) measured at various temperatures are used to estimate the wavefunction phase breakdown length L of conduction electrons and to obtain the temperature dependence L = const T, where p ≈ 1/3. Similar dependences of electrical conductivity σ( T), magnetoresistivity ρ( B), and phase breakdown length L( T) are detected for the initial MWCNTs used to prepare the paper.
