Figure 11: (a) Schematic view of a molecule coupled to source and drain contacts. (b) The molecule is described by a Hamiltonian H and a self-consistent potential 𝑈 𝑆 𝐶 . The effect of the large contacts is described using self-energy matrices Σ 1 , 2 . Scattering processes may be described using another self-energy matrix Σ 𝑝 . The source and drain contacts are identified by their respective Fermi levels 𝜇 1 and 𝜇 2 .
