Kondo Physics in Nanotubes: Magnetic-field dependence and singlet-triplet Kondo
C. H. L. Quay, John Cumings, Sara Gamble +3
In a single-walled carbon nanotube, we observe the spin-1/2 Kondo effect. The energy of spin-resolved Kondo peaks is proportional to magnetic field at high fields, contrary to rece…
Transport Properties of Carbon Nanotube C Peapods
C. H. L. Quay, John Cumings, S. J. Gamble +4
We measure the conductance of carbon nanotube peapods from room temperature down to 250mK. Our devices show both metallic and semiconducting behavior at room temperature. At the lo…
High mobility two-dimensional hole system in GaAs/AlGaAs quantum wells grown on (100) GaAs substrates
M. J. Manfra, L. N. Pfeiffer, K. W. West +2
We report on the transport properties of a high mobility two-dimensional hole system (2DHS) confined in GaAs/AlGaAs quantum wells grown molecular-beam epitaxy on the (100) surface…
Many-body dispersions in interacting ballistic quantum wires
Ophir M. Auslaender, Hadar Steinberg, Amir Yacoby +6
We have measured the collective excitation spectrum of interacting electrons in one-dimension. The experiment consists of controlling the energy and momentum of electrons tunneling…
Observation of a Fifth of the Electron Charge
M. Reznikov, R. de Picciotto, T. G. Griffiths +2
We report the observation of quasi-particles with a charge q=e/5 detected by shot noise measurements in the 2/5 conducting channel (filling factor 2/5). This is in agreement with p…
