  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 other types of behaviours 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 thermalisation 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.
