Before revision:  Apart from periodic segments , which display enhanced transport properties , there are several cases of deterministic aperiodic sequences that can support significant currents, depending on the Fermi level of the leads.
After revision:  Apart from periodic segments , which display enhanced transport properties . Specifically, in homogeneous sequences transport efficiency is maximum. There are several deterministic aperiodic sequences that can support significant currents, depending on the Fermi level of the leads.
