Two-Stage Kondo Effect and Kondo Box Level Spectroscopy in a Carbon Nanotube
Yu. Bomze, I. Borzenets, H. Mebrahtu +3
The concept of the "Kondo box" describes a single spin, antiferromagnetically coupled to a quantum dot with a finite level spacing. Here, a Kondo box is formed in a carbon nanotube…
Resonant Tunneling in a Dissipative Environment
Yu. Bomze, H. Mebrahtu, I. Borzenets +2
We measure tunneling through a single quantum level in a carbon nanotube quantum dot connected to resistive metal leads. For the electrons tunneling to/from the nanotube, the leads…
Four-Probe Measurements of Carbon Nanotubes with Narrow Metal Contacts
A. Makarovski, A. Zhukov, J. Liu +1
We find that electrons in single-wall carbon nanotubes may propagate substantial distances (tens of nanometers) under the metal contacts. We perform four-probe transport measuremen…
SU(4) and SU(2) Kondo Effects in Carbon Nanotube Quantum Dots
A. Makarovski, A. Zhukov, J. Liu +1
We study the SU(4) Kondo effect in carbon nanotube quantum dots, where doubly degenerate orbitals form 4-electron ``shells''. The SU(4) Kondo behavior is investigated for one, two…
Evolution of SU(4) Transport Regimes in Carbon Nanotube Quantum Dots
A. Makarovski, J. Liu, G. Finkelstein
We study the evolution of conductance regimes in carbon nanotubes with doubly degenerate orbitals (``shells'') by controlling the contact transparency within the same sample. For s…
Persistent Orbital Degeneracy in Carbon Nanotubes
A. Makarovski, L. An, J. Liu +1
The quantum-mechanical orbitals in carbon nanotubes are doubly degenerate over a large number of states in the Coulomb blockade regime. We argue that this experimental observation…
