Single molecule junctions, where individual molecules are placed between two nano-electrodes, are ideal systems to create molecular-scale functional materials with the desired electronic properties. The flow of an electrical current across the junction depends on molecular chemical properties and on the atomistic details of the contacts to the electrodes, which are thus essential to characterize. This project will design and characterize single molecule circuits with tailored mechanical, conducting and thermoelectric properties. To achieve this, we will combine chemical synthesis, atomistic simulations, and a series of experimental measurements including electron transport break-junction methods and optical spectroscopies. To better describe the conditions of any potential technological applications in nanoelectronics, they will study these materials at room temperature.

They expect the project to deepen the understanding into the fundamental mechanisms governing current flow, to generate insight into the atomic-scale structure at the interface, and to develop experimental techniques to manipulate the junctions and tune their conducting properties. These findings will chart new pathways for delivering molecular junctions with tailored properties.
