Highly Reproducible Formation of a Polymer Single‐Molecule Junction for a Well‐Defined Current Signal. (27th May 2019) - Harashima, Takanori
Abstract: Single‐molecule devices attract much interest in the development of nanoscale electronics. Although a variety of functional single molecules for single‐molecule electronics have been developed, there still remains the need to implement sophisticated functionalization toward practical applications. Given its superior functionality encountered in macroscopic materials, a polymer could be a useful building block in the single‐molecule devices. Therefore, a molecular junction composed of polymer has now been created. Furthermore, an automated algorithm was developed to quantitatively analyze the tunneling current through the junction. Quantitative analysis revealed that the polymer junction exhibits a higher formation probability and longer lifetime than its monomer counterpart. These results suggest that the polymer provides a unique opportunity to design both stable and highly functional molecular devices for nanoelectronics. Abstract : Die molekulare Kontaktstelle eines Polymers, das spontan in einer Metall‐Nanolücke gebildet wird, wurde untersucht. Das Polymer bildet eine stabilere molekulare Kontaktstelle mit höherer Bildungswahrscheinlichkeit als das entsprechende Monomer. Die Ergebnisse legen nahe, dass Polymere attraktive Bausteine für nanoelektrische Geräte mit erweiterten Funktionalitäten sind.
