Mapping electron delocalization by charge transport spectroscopy in an artificial molecule
M. R. Graeber, M. Weiss, D. Keller +2
In this letter we present an experimental realization of the quantum mechanics textbook example of two interacting electronic quantum states that hybridize forming a molecular stat…
Even-odd effect in Andreev Transport through a Carbon Nanotube Quantum Dot
A. Eichler, M. Weiss, S. Oberholzer +3
We have measured the current(I)-voltage(V) characteristics of a single-wall carbon nanotube quantum dot coupled to superconducting source and drain contacts in the intermediate cou…
Defining and controlling double quantum dots in single-walled carbon nanotubes
M. R. Graeber, M. Weiss, C. Schoenenberger
We report the experimental realization of double quantum dots in single-walled carbon nanotubes. The device consists of a nanotube with source and drain contact, and three addition…
Molecular states in carbon nanotube double quantum dots
M. R. Graeber, W. A. Coish, C. Hoffmann +5
We report electrical transport measurements through a semiconducting single-walled carbon nanotube (SWNT) with three additional top-gates. At low temperatures the system acts as a…
Positive Cross Correlations in a Normal-Conducting Fermionic Beam Splitter
S. Oberholzer, E. Bieri, C. Schoenenberger +2
We investigate a beam splitter experiment implemented in a normal conducting fermionic electron gas in the quantum Hall regime. The cross-correlations between the current fluctuati…
Shot-noise and conductance measurements of transparent superconductor / two-dimensional electron gas junctions
B. -R. Choi, A. E. Hansen, T. Kontos +6
We have measured the conductance and shot-noise of superconductor-normal metal (S-N) junctions between a Niobium (Nb) film and a 2-dimensional electron gas (2DEG), formed in an InA…
