Disordered effect on a graphene-based spin–orbit interactions superlattice

The transmission character in the present superlattice under the influence of disorder is considered. It is shown that transmission coefficients are sensitive to the disorder strength and the system size. In particular, the Klein tunneling can be suppressed by disorder to a neglectable value only when the ISOI exists. In addition, the transmission channel through the system in the normal incidence case can be tuned by the system size only when the RSOI exists. The physical origination of those phenomena has also been analyzed.
