Dynamic Control of Plasmon Generation by an Individual Quantum System

Klaus Kern, Markus Etzkorn, Uta Schlickum, Romain Froidevaux, Theresa Lutz, Christoph Grosse, Alexander Kabakchiev

Controlling light on the nanoscale in a similar way as electric currents has the potential to revolutionize the exchange and processing of information. Although light can be guided on this scale by coupling it to plasmons, that is, collective electron osci ...

Molecular Orbital Gates for Plasmon Excitation

Klaus Kern, Uta Schlickum, Christian Alexander Stephan Dette, Theresa Lutz, Christoph Grosse, Alexander Kabakchiev

Future combinations of plasmonics with nanometer-size electronic circuits require strategies to control the electrical excitation of plasmons at the length scale of individual molecules. A unique tool to study the electrical plasmon excitation with ultimat ...

Surface morphology of MnSi thin films grown on Si(111)

Klaus Kern, Theresa Lutz, Giovanni Costantini

The surface morphology of MnSi thin films grown on Si(111)-7 x 7 substrates was investigated by systematically changing the amount of deposited Mn. A new 3 x 3 surface reconstruction was found at the very initial growth stages, whose atomic configuration w ...

Electroluminescence properties of organic nanostructures studied by scanning tunnelling microscopy

Klaus Kern, Theresa Lutz, Alexander Kabakchiev

The control of light emission on the scale of individual quantum systems, like molecules or quantum dots, is a field of intense current research. One way to induce light emission from these systems is the local charge injection through the tip of a scannin ...

Growth mode and atomic structure of MnSi thin films on Si(111)

Klaus Kern, Theresa Lutz, Giovanni Costantini

Thin films of MnSi(111) in B20 structure formed by reactive epitaxy on Si(111) are studied using scanning tunneling microscopy (STM) and density functional theory calculations. Coexisting root 3 x root 3 structures with high or low corrugation are observed ...

Scanning Tunneling Microscopy and Luminescence of Individual Nanostructures

Theresa Lutz

A detailed investigation and characterization of the local properties of individual nanoscopic structures is of great importance for the understanding of novel physical phenomena at the nanoscale as well as for the assessment of their possible use in futur ...

Terephthalic acid adsorption on Si(111)-(root 3x root 3)-Bi surfaces: Effect of Bi coverage

Klaus Kern, Theresa Lutz, Giovanni Costantini

The influence of the density of metallic atoms on the formation of supramolecular structures onto Si surface alloys is investigated by scanning tunneling microscopy. Terephthalic acid (TPA) adsorption experiments are performed on the Si(111) alpha- and bet ...

Scanning Tunneling Luminescence of Individual CdSe Nanowires

Klaus Kern, Marko Burghard, Zhe Wang, Theresa Lutz, Alexander Kabakchiev, Thomas Dufaux

The local luminescence properties of individual CdSe nanowires composed of segments of zinc blende and wurtzite crystal structures are investigated by low-temperature scanning tunneling luminescence spectroscopy. Light emission from the wires is achieved b ...
