Molecular electronics offers new ways for scaling down nanoelectronic components and making their production and operation more energy efficient. Our research focuses on classifying different molecules with the help of Mechanically Controlled Break Junction (MCBJ).
Here, we perform measurements on salen molecule and metal-salen complexes in liquid environments. They are explored as candidates for “chemical doping”, because they provide the possibility to fine-tune electrical properties by using different molecular inclusions. We measure both constant voltage vs. distance and IV characteristic of our metal-molecule-metal junctions.
Measurements are then fitted to a theoretical model, which takes the contribution of a single molecular level into account. From this model the energy of the molecular level and the coupling to the electrodes can be extracted and compared to first principles calculations.
