Chirality is a geometric property of matter that can be present at different scales, especially at the nanoscale. We investigate the manifestation of chirality in electronic transport through a molecular junction when a chiral metal cluster is attached to the source electrode. We obtained a different spinless electronic transport between R and L molecules due to the presence of the chiral metal cluster. To evaluate electronic transport, we use the non-equilibrium Green’s function method. Our theoretical results highlight the importance of metal clusters with specific sizes and chiral structures in electronic transport and support previously published experimental results [1] that exhibited chiral-dependent scanning tunneling measurements with intrinsically chiral tips.
