An electrical model was developed to describe the electronic transport in carbon nanotube (CNT)-based materials. Our model successfully fits the literature data and highlights the role played by different mechanisms (Luttinger Liquid, metallic and semiconducting behaviors) depending on the temperature range (3–300 K) and on the fabrication technique (floating catalyst carbon nanotube yarns or carbon nanotube array yarns). It appears that the CNT growth control is much more important than the fabrication technique to allow for high electrical conductivity CNT yarns.
