摘要：

By using an order N quantum transport methodology, and treating on the same footing static and dynamical disorders, we report on the theoretical exploration of quantum interferences tuned by electronphonon mediated decoherence mechanisms in disordered carbon nanotubes (with length up to 10 mu m). This allows the extraction of inelastic scattering times together with temperature-dependent coherence lengths, which favorably compare with available experimental data at a quantitative level, and clarify the role of localization phenomena up to room temperature.
