Low-dimensional quantum transport properties of chemically-disordered carbon nanotubes: From weak to strong localization regimes

In this review, the quantum transport of nitrogen-doped metallic carbon nanotubes under magnetic field are explored. An accurate modeling of chemical disorder effects is derived from ab initio calculations. General properties for low bias Landauer conductance are investigated in the coherent regime, which enlighten the strong interplay between band structure and quantum interference effects. Characteristic transport length scales such as the elastic mean free path and localization length are extracted from phenomenological laws as well as scaling features with nanotube radius and doping level. The statistical analysis of conductance properties allow us to study the transition between weak and strong localization regimes.
