Coulomb Blockade Fluctuations in Strongly Coupled Quantum Dots
نویسندگان
چکیده
Quantum fluctuations of the Coulomb blockade are investigated as a function of the coupling to reservoirs in semiconductor quantum dots. We use fluctuations in the distance between peaks DN apart to characterize both the amplitude and correlation of peak motion. For strong coupling, the peak motion is greatly enhanced at low temperature, but does not show the expected increase in peak-topeak correlation. These effects can lead to anomalous temperature dependence in the Coulomb valleys, similar to the behavior ascribed to Kondo physics.

متن کاملExchange and the Coulomb blockade: Peak height statistics in quantum dots
We study the effect of the exchange interaction on the Coulomb blockade peak height statistics in chaotic quantum dots. Since exchange reduces the level repulsion in the many-body spectrum, it strongly affects the fluctuations of the peak conductance at finite temperature. We find that including exchange substantially improves the description of the experimental data. Moreover, it provides furt...
متن کاملTheoretical and experimental investigations of Coulomb blockade in coupled quantum dot systems.
Two strongly coupled quantum dots are theoretically and experimentally investigated. In conductance measurements on a GaAs based low-dimensional system additional features to the Coulomb blockade have been detected at low temperatures. These regions of finite conductivity are compared with theoretical investigations of a strongly coupled quantum dot system and good agreement between the theoret...
متن کاملChapter 3 . Coulomb Blockade In Single And Double Quantum Dots
A few years ago, Professor Kastner's research group discovered that the conductance through a quantum dot weakly coupled to the leads shows periodic peaks as a function of the voltage on a gate electrode. 1 This behavior was attributed to the phenomenon of Coulomb blockade: to add an electron to the dot, the system must have an energy equal to the electrostatic energy of a dot charged by one el...
متن کاملMesoscopic Coulomb Blockade in One-Channel Quantum Dots
Signatures of “mesoscopic Coulomb blockade” are reported for quantum dots with one fully transmitting point-contact lead; T1 1, T2 ø 1. Unlike the Coulomb blockade (CB) in weaktunneling devices sT1, T2 ø 1d, one-channel CB is a mesoscopic effect requiring quantum coherence. Several distinctive features of mesoscopic CB are observed, including a reduction in CB upon breaking time-reversal symm...
