Time-dependent universal conductance fluctuations and coherence in AuPd and Ag
A. Trionfi, S. Lee, D. Natelson
Quantum transport phenomena allow experimental assessment of the phase coherence information in metals. We report quantitative comparisons of coherence lengths inferred from weak l…
Quantum coherence in a ferromagnetic metal: time-dependent conductance fluctuations
S. Lee, A. Trionfi, D. Natelson
Quantum coherence of electrons in ferromagnetic metals is difficult to assess experimentally. We report the first measurements of time-dependent universal conductance fluctuations…
Inelastic electron tunneling via molecular vibrations in single-molecule transistors
L. H. Yu, Z. K. Keane, J. W. Ciszek +4
In single-molecule transistors, we observe inelastic cotunneling features that correspond energetically to vibrational excitations of the molecule, as determined by Raman and infra…
Electronic coherence in metals: comparing weak localization and time-dependent conductance fluctuations
A. Trionfi, S. Lee, D. Natelson
Quantum corrections to the conductivity allow experimental assessment of electronic coherence in metals. We consider whether independent measurements of different corrections are q…
Transport in single-molecule transistors: Kondo physics and negative differential resistance
L. H. Yu, D. Natelson
We report two examples of transport phenomena based on sharp features in the effective density of states of molecular-scale transistors: Kondo physics in C-based devices, an…
