Knowing the feature size of the domination of tunneling leakage in molecular electronics is of fundamental significance, which enhances the understanding of the technical limitations and boundaries for using single-molecule components as electronic devices. An international team of researchers (China, UK, Switzerland) investigated the transition distance between through-space tunneling and molecular tunneling using the oligo(aryleneethynylene) molecules. They demonstrated that molecular tunneling can be distinguished and outstripped from the tunneling leakage down to the size of 0.66 nm, suggesting the potential to push the miniaturization limit of molecular electronic devices to the angstrom scale…read more.

For the shortest OAE molecule, the intrinsic single-molecule charge transport can be outstripped from tunneling leakage at 0.66 nm, suggesting the potential to push the miniaturization limit of molecular electronic devices to the angstrom scale. CREDIT: Xiamen University
