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 ...

Electron quantization in arbitrarily shaped gold islands on MgO thin films

Wolf-Dieter Schneider

Low-temperature scanning tunneling microscopy has been employed to analyze the formation of quantum well states (QWS) in two-dimensional gold islands, containing between 50 and 200 atoms, on MgO thin films. The energy position and symmetry of the eigenstat ...

Growth of Two-Dimensional Lithium Islands on CaO(001) Thin Films

Wolf-Dieter Schneider

The nucleation and growth behavior of lithium on a CaO/Mo(001) thin film has been investigated by means of scanning tunneling microscopy and spectroscopy. The Li follows two different growth regimes on the surface. Whereas extended 2D islands develop on to ...

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

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 ...

Plasmon enhanced luminescence from fullerene molecules excited by local electron tunneling

Wolf-Dieter Schneider, François Patthey, Marina Pivetta

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 ...

Engineering Spin Interaction Channels of FePc on Au(111)

Wolf-Dieter Schneider

We demonstrate the reversible control of interactions between a local molecular spin, hosted within an iron phthalocyanine (FePc) molecule, and the conduction electrons of a supporting Au(111) surface. Using the tip of a scanning tunneling microscope, we d ...

Highlights of the Science and Life of Peter Varga (1946-2018)

Wolf-Dieter Schneider

Peter Varga has passed on October 27, 2018. His pioneering discoveries of chemical resolution at the atomic scale on surface alloys, atomic resolution of ultrathin alkali halides, nucleation of bcc iron in ultrathin films, and the microscopic structure of ...

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 ...

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

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

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, ...

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

Wolf-Dieter Schneider, François Patthey

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 ...

Phonon-Mediated Electron Transport through CaO Thin Films

Wolf-Dieter Schneider, Giulia Elisabetta Pacchioni

Scanning tunneling microscopy has developed into a powerful tool for the characterization of conductive surfaces, for which the overlap of tip and sample wave functions determines the image contrast. On insulating layers, as the CaO thin film grown on Mo(0 ...
