Salomon, Adi published the artcileStable Room-Temperature Molecular Negative Differential Resistance Based on Molecule-Electrode Interface Chemistry, COA of Formula: C15H29BrO2, the main research area is stable room temperature mol neg resistance mol electrode interface.
The authors show reproducible, stable neg. differential resistance (NDR) at room temperature in mol.-controlled, solvent-free devices, based on reversible changes in mol.-electrode interface properties. The active component is the cyclic disulfide end of mols. adsorbed onto Hg. As this active component is reduced, the Hg-mol. contact is broken, and an insulating barrier at the mol.-electrode interface is formed. Therefore, the alignment of the mol. energy levels, relative to the Fermi levels of the electrodes, is changed. This effect results in a decrease in the current with voltage increase as the reduction process progresses, leading to the so-called NDR behavior. The effect is reproducible and repeatable over >50 scans without any reduction in the current. The stability of the system, which is in the solid state except for the Hg, is due to the mol. design where long alkyl chains keep the mols. aligned with respect to the Hg electrode, even when they are not bound to it any longer.
