By using Scanning Tunneling Microscope (STM) and the Break Junction approach, this study reveals that organic solvents are not fully evaporated on gold substrates and characterizes their electronic transport properties in molecular electronics.
After evaporation of the organic solvents, benzene, toluene, and cyclohexane on gold substrates, Scanning Tunneling Microscope (STM) shows the presence of a remaining adsorbed layer. The different solvent molecules were individually observed at ambient conditions, and their electronic transport properties characterized through the STM in the Break Junction approach. The combination of both techniques reveals, on one hand, that solvents are not fully evaporated over the gold electrode and, secondly, characterize the electronic transport of the solvents in molecular electronics.
