Spin Degeneracy and Conductance Fluctuations in Open Quantum Dots
J. A. Folk, S. R. Patel, K. M. Birnbaum +3
The dependence of mesoscopic conductance fluctuations on parallel magnetic field is used as a probe of spin degeneracy in open GaAs quantum dots. The variance of fluctuations at hi…
Low-Temperature Saturation of the Dephasing Time and Effects of Microwave Radiation on Open Quantum Dots
A. G. Huibers, J. A. Folk, S. R. Patel +3
The dephasing time of electrons in open semiconductor quantum dots, measured using ballistic weak localization, is found to saturate below ~ 100 mK, roughly twice the electron base…
Coulomb Blockade Fluctuations in Strongly Coupled Quantum Dots
S. M. Maurer, S. R. Patel, C. M. Marcus +2
Quantum fluctuations of Coulomb blockade are investigated as a function of the coupling to reservoirs in semiconductor quantum dots. We use fluctuations in the distance between pea…
Changing the Electronic Spectrum of a Quantum Dot by Adding Electrons
S. R. Patel, D. R. Stewart, C. M. Marcus +5
The temperature dependence of Coulomb blockade peak height correlation is used to investigate how adding electrons to a quantum dot alters or "scrambles" its electronic spectrum. D…
Mesoscopic Coulomb Blockade in One-channel Quantum Dots
S. M. Cronenwett, S. M. Maurer, S. R. Patel +3
Signatures of "mesoscopic Coulomb blockade" are reported for quantum dots with one fully transmitting point-contact lead, T1 = 1, T2 << 1. Unlike Coulomb blockade (CB) in weak-tunn…
Distributions of the Conductance and its Parametric Derivatives in Quantum Dots
A. G. Huibers, S. R. Patel, C. M. Marcus +3
Full distributions of conductance through quantum dots with single-mode leads are reported for both broken and unbroken time-reversal symmetry. Distributions are nongaussian and ag…
Statistics of Coulomb Blockade Peak Spacings
S. R. Patel, S. M. Cronenwett, D. R. Stewart +6
Distributions of Coulomb blockade peak spacing are reported for large ensembles of both unbroken (magnetic field B = 0) and broken (B <> 0) time reversal symmetry in GaAs quantum d…
