Electrical conductance of molecular junctions by a robust statistical analysis (2006)

González, M. Teresa, Wu, Songmei, Huber, Roman, Van Der Molen, Sense J., Schönenberger, Christian, Calame, Michel

We propose an objective and robust method to extract the electrical conductance of single molecules connected to metal electrodes from a set of measured conductance data. Our method roots in the...

Controlling spin in an electronic interferometer with spin-active interfaces (2006)

Cottet, Audrey, Kontos, Takis, Belzig, Wolfgang, Schönenberger, Christian, Bruder, Christoph

We consider electronic current transport through a ballistic one-dimensional quantum wire connected to two ferromagnetic leads. We study the effects of the spin-dependence of interfacial phase shifts...

Electric Field Control of Spin Transport (2005)

Sahoo, Sangeeta, Kontos, Takis, Furer, Jürg, Hoffmann, Christian, Gräber, Matthias, Cottet, Audrey, ...

Spintronics is an approach to electronics in which the spin of the electrons is exploited to control the electric resistance R of devices. One basic building block is the spin-valve, which is formed...

Shot-noise and conductance measurements of transparent superconductor/two-dimensional electron gas junctions (2005)

Choi, Bong-Ryoul, Hansen, A. E., Kontos, Takis, Hoffmann, M., Oberholzer, Stefan, Belzig, Wolfgang, ...

We have measured the conductance and shot noise of superconductor-normal metal (S-N) junctions between a niobium (Nb) film and a two-dimensional electron gas (2DEG), formed in an InAs-based...

Quantum dot coupled to a normal and a superconducting lead (2004)

Gräber, Matthias R., Nussbaumer, T., Belzig, Wolfgang, Schönenberger, Christian

We report on electrical transport measurements in a carbon nanotube quantum dot coupled to a normal and a superconducting lead. Depending on the ratio of Kondo temperature TK and superconducting gap...

Multiple Andreev reflections in a carbon nanotube quantum dot (2003)

Buitelaar, Mark R., Belzig, Wolfgang, Nussbaumer, Thomas, Babic, Bakir, Bruder, Christoph, Schönenberger, Christian

We report resonant multiple Andreev reflections in a multiwall carbon nanotube quantum dot coupled to superconducting leads. The position and magnitude of the subharmonic gap structure is found to...

UHV compatible nanostructuring technique for mesoscopic hybrid devices: application to superconductor/ferromagnet Josephson contacts (2002)

Hoss, T, Strunk, Christoph, Sürgers, C., Schönenberger, Christian

We report on an ultra-high vacuum (UHV) compatible method for fabricating devices of sub-micrometer size by virtue of a non-organic evaporation mask of high thermal and mechanical stability. As an...

Doping state of multi-wall carbon nanotubes wires and quantum dots (2001)

Schönenberger, Christian, Buitelaar, Mark, Krüger, Michael, Widmer, Isabelle, Nussbaumer, Thomas, Iqbal, Mahdi

Employing strong electrostatic gating (liquid-ion gating), the position of the Fermi energy E_F (relative to the charge-neutrality point) was determined in multi-wall carbon nanotubes (MWNTs). E_F is...

Aharonov-Bohm oscillations in carbon nanotubes (1999)

Bachtold, Adrian, Strunk, Christoph, Salvetat, Jean-Paul, Bonard, Jean-Marc, Forro, Laszlo, Nussbaumer, Thomas, ...

When electrons pass through a cylindrical electrical conductor aligned in a magnetic field, their wave-like nature manifests itself as a periodic oscillation in the electrical resistance as a...

Size Dependent Thermopower in Mesoscopic AuFe Wires (1998)

Strunk, Christoph, Henny, M., Schönenberger, Christian, Neuttiens, G., Van Haesendonck, C.

We have combined electron heating experiments and noise thermometry to perform quantitative measurements of the thermopower in mesoscopic samples. This new measuring technique allows us to detect...
