Query: Tunable transmission due to defects in zigzag phosphorene nanoribbons   Transport of the edge-state electrons along zigzag phosphorene nanoribbons in
presence of two impurities/vacancies is analytically investigated. Considering
the places of the defects, a number of different situations are examined. When
both defects are placed on the edge zigzag chain, as is expected, with changing
the energy of the traveling electrons the electrical conductance exhibits a
resonance behavior. In this case, for two vacancies the observed resonant peaks
become extremely sharp. An amazing behavior is seen when the second vacancy is
located along an armchair chain while the first is placed at the intersection
of the edge zigzag and this armchair chains. In this case, in a considerable
range of energy, the conductance is strongly strengthened. In fact the presence
of the second vacancy create a shielded region around the first vacancy,
consequently, the traveling wave bypasses this region and enhances the
conductivity. The analytical results are compared with numerical simulations
showing a very good agreement.
