Dissociation of oxygen on Ag(100) induced by inelastic electron tunneling

This article reviews manipulation of single molecules by scanning tunnelling microscopes, in particular vertical manipulation, lateral manipulation, and inelastic electron tunnelling (IET) manipulation. For a better understanding of these processes, we shortly review imaging by scanning tunnelling microscopy – as a prerequisite to detect the manipulated species and to verify the result of the manipulation – as well as scanning tunnelling spectroscopy and IET spectroscopy which are used to chemically identify the molecules before and after the manipulation that employs the tunnelling current.

“…In contrast, the ejection of electrons from the O 2 molecule produced adsorbed O atoms separated along the [001] direction. However, the dissociation of O 2 on the Ag(100) surface took place at a high threshold bias voltage of +3.3 V, with the produced atom pairs showing a broad range of motions and immediately pulling each other apart …”

[43] Dissociation processes induced by inelastic electron tunneling are extremely popular among on-surface reactions; in light of this,atomic-scale knowledge of the dissociation of diatomic molecules is ap rerequisite for understanding more complicated surface reactions.B yt unneling electrons into amolecule at aspecific position, precise rupture of abond can be attained, eventually cleaving off unnecessary parts of am olecule and generating active sites.T he molecular fragments obtained may further be used as building blocks for new chemical species.…”

Scanning probe microscopy (SPM) is a powerful tool to study the structure and dynamics of molecules at surfaces and interfaces as well as to precisely manipulate atoms and molecules by applying an external force, by inelastic electron tunneling, or by means of an electric field. The rapid development of these SPM manipulation modes made it possible to achieve fine‐control over fundamental processes in the physics of interfaces as well as chemical reactivity, such as adsorption, diffusion, bond formation, and bond dissociation with precision at the single atom/molecule level. Their controlled use for the fabrication of atomic‐scale structures and synthesis of new, perhaps uncommon, molecules with programmed properties are reviewed. Opportunities and challenges towards the development of complex chemical systems are discussed, by analyzing potential future impacts in nanoscience and nanotechnology.

“…Im Unterschied dazu erzeugte der Ausstoß von Elektronen aus dem O 2 ‐Molekül adsorbierte Sauerstoffatome, die entlang der [001]‐Richtung getrennt waren. Die Dissoziation von O 2 auf Ag(100) erfolgte jedoch bei einer hohen Vorspannung von +3.3 V, und die erzeugten Atompaare wiesen eine breite radiale Verteilung auf …”

Rastersondenmikroskopische (SPM‐)Verfahren sind leistungsfähige Hilfsmittel, um die Struktur und Dynamik von Molekülen an Oberflächen und Grenzflächen zu untersuchen sowie Atome und Moleküle durch äußere Krafteinwirkung, durch inelastisches Elektronentunneln oder durch ein elektrisches Feld präzise zu steuern. Die schnelle Entwicklung dieser SPM‐Manipulationsmodi ermöglichte es, eine Feinsteuerung der grundlegenden Prozesse in der Physik der Grenzflächen und der chemischen Reaktivität, darunter Adsorption, Diffusion, Bindungsbildung sowie ‐dissoziation, mit einer Präzision auf Einzelatom‐/Molekülebene zu erreichen. Ihre kontrollierte Anwendung zur Herstellung atomskaliger Strukturen und die Synthese neuer, auch außergewöhnlicher Moleküle mit programmierten Eigenschaften werden vorgestellt. Es werden die Möglichkeiten und Herausforderungen bezüglich der Entwicklung komplexer chemischer Systeme diskutiert, indem mögliche zukünftige Auswirkungen auf die Nanowissenschaften und die industrielle Nanotechnologie analysiert werden.
