In this paper, to understand the concept of coupling, molecule density of states that coupled to the metal electrodes will be explained then, based on this concept, a weak and strong coupling for the molecules attached to the metal electrodes will be described. Capacitance model is used to explore the connection of addition energy with the Electron affinity and the ionization energy of the mole...

The large, level-dependent g factors in an InSb nanowire quantum dot allow for the occurrence of a variety of level crossings in the dot. While we observe the standard conductance enhancement in the Coulomb blockade region for aligned levels with different spins due to the Kondo effect, a vanishing of the conductance is found at the alignment of levels with equal spins. This conductance suppres...

Conduction of electro-migration gap junctions coated with various organic molecules is studied to expose the prevalence of different transport processes. The principal comparison made here is between molecules with conjugated versus non-conjugated backbones. Coulomb blockade (CB) is observed in all junctions, including bare junctions and those with non-conjugated molecules, but at significantly...
