This paper presents experimental evidence that a parallel circuit in
molecular electronics setting does not obey the Kirchhoff Rule, which
states that the conductance of a parallel circuit is a sum of the
parallel parts. In this case, quantum interference is held as the
culprit, giving rise to higher conductance! (actual conductance ~ 1.5 x
that predicted by Kirchhoff). Measurements were done using STM-break
junction experiments, as well as DFT.
