The one-dimensional
confinement of quasiparticles in individual
carbon nanotubes (CNTs) leads to extremely anisotropic electronic
and optical properties. In a macroscopic ensemble of randomly oriented
CNTs, this anisotropy disappears together with other properties that
make them attractive for certain device applications. The question
however remains if not only anisotropy but also other types of behaviors
are suppressed by disorder. Here, we compare the dynamics of quasiparticles
under strong electric fields in aligned and random CNT networks using
a combination of terahertz emission and photocurrent experiments and
out-of-equilibrium numerical simulations. We find that the degree
of alignment strongly influences the excited quasiparticles’
dynamics, rerouting the thermalization pathways. This is, in particular,
evidenced in the high-energy, high-momentum electronic population
(probed through the formation of low energy excitons via exciton impact
ionization) and the transport regime evolving from diffusive to superdiffusive.
