a Schematic illustration of the Ag–S(CH2)nX//GaOx/EGaIn junction (shown for n = 14, EGaIn is for eutectic alloy of Gallium and Indium, “-” represents covalent bond, “//” represents non-covalent contact, “/” means the interface between GaOx and EGaIn) together with the equivalent circuit diagram. In this work we investigated junctions with n = 10, 12, 14, 16, or 18, and X = H, F, Cl, Br, or I. b Energy level diagram of the junction showing how the coupling strength between molecules and electrodes (Γ) and tunnelling barrier height (δEME) change with X.
