Dynamical Coulomb Blockade Observed in Nanosized Electrical Contacts

Wolf-Dieter Schneider, François Patthey, I-Po Hong

Electrical contacts between nanoengineered systems are expected to constitute the basic building blocks of future nanoscale electronics. However, the accurate characterization and understanding of electrical contacts at the nanoscale is an experimentally c ...

Growth and characterization of fullerene nanocrystals on NaCl/Au(111)

Wolf-Dieter Schneider, François Patthey, Marina Pivetta, Elizabeta Cavar, Frédéric Rossel

The growth of fullerene nanocrystals, composed of only C-60, only C-70, or a mixture of both fullerenes, has been investigated by scanning tunneling microscopy (STM). The nanocrystals, formed on a NaCl ultrathin layer partially covering a Au(111) surface, ...

Supramolecular Self-Assembly Driven by Electrostatic Repulsion: The 1D Aggregation of Rubrene Pentagons on Au(111)

Wolf-Dieter Schneider, Alfonso Baldereschi, Massimiliano Stengel

At present, organic molecules are among the best candidate "building blocks" for the construction of self-assembling nanoscale devices based on metal substrates. Control of the formation of specific patterns In the submonolayer regime is usually achieved b ...

Melting of Two-Dimensional Adatom Superlattices Stabilized by Long-Range Electronic Interactions

François Patthey, Wolf-Dieter Schneider, Marina Pivetta, Markus Ternes

The melting transition of Ce adatom superlattices stabilized by long-range substrate-mediated electronic interactions on Cu(111) and Ag(111) noble metal surfaces has been investigated by low-temperature scanning tunneling microscopy, density functional the ...

Plasmon enhanced luminescence from fullerene molecules excited by local electron tunneling

Wolf-Dieter Schneider, François Patthey, Marina Pivetta, Frédéric Rossel

Tunneling electrons from a scanning tunneling microscope (STM) induce luminescence from C-60 and C-70 molecules forming fullerene nanocrystals grown on ultrathin NaCl films on Au(111). Intramolecular. uorescence and phosphorescence associated with the tran ...

Spectroscopic manifestations of the Kondo effect on single adatoms

Wolf-Dieter Schneider, Markus Ternes

The present topical review focuses on recent advances concerning an intriguing phenomenon in condensed matter physics, the scattering of conduction electrons at the localized spin of a magnetic impurity: the Kondo effect. Spectroscopic signatures of this e ...

Three-Dimensional Chirality Transfer in Rubrene Multilayer Islands on Au(111)

Wolf-Dieter Schneider, François Patthey, Marina Pivetta

The growth of rubrene (C42H28, 5,6,11,12-tetraphenylnaphthacene) multilayer islands up to a thickness of six layers on a Au(111) surface has been investigated by scanning tunneling microscopy. The molecules self-organize in parallel twin rows, forming mirr ...

Reduction of the Superconducting Gap of Ultrathin Pb Islands Grown on Si(111)

Wolf-Dieter Schneider, François Patthey, I-Po Hong

The energy gap Delta of superconducting Pb islands grown on Si(111) was probed in situ between 5 and 60 monolayers by low-temperature scanning tunneling spectroscopy. Delta was found to decrease from its bulk value as a function of inverse island thickness ...

Decay mechanisms of excited electrons in quantum-well states of ultrathin Pb islands grown on Si(111): Scanning tunneling spectroscopy and theory

Wolf-Dieter Schneider, François Patthey, I-Po Hong

Using low-temperature scanning tunneling spectroscopy at 5 and 50 K, we studied the linewidth of unoccupied quantum-well states in ultrathin Pb islands, grown on Si(111) on two different Pb/Si interfaces. A quantitative analysis of the differential conduct ...

Modified herringbone reconstruction on Au(111) induced by self-assembled Azure A islands

Wolf-Dieter Schneider, François Patthey, Frédéric Rossel

Upon submonolayer deposition of Azure A molecules onto reconstructed Au(1 1 1), two-dimensional quasi-rectangular islands are observed by low-temperature scanning tunneling microscopy. Strikingly, the 22 x root 3 reconstruction with alternating hexagonal c ...
