Coulomb blockade of tunneling through a double quantum dot.
We study the Coulomb blockade of tunneling through a double quantum dot. The temperature dependence of the linear conductance is strongly affected by the interdot tunneling. As the tunneling grows, a crossover from temperature-independent peak conductance to a power-law suppression of conductance at low temperatures is predicted. This suppression is a manifestation of the Anderson orthogonality...
متن کاملCoulomb blockade in an open quantum dot.
We report the observation of Coulomb blockade in a quantum dot contacted by two quantum point contacts each with a single fully transmitting mode, a system thought to be well described without invoking Coulomb interactions. Below 50 mK we observe a periodic oscillation in the conductance of the dot with gate voltage, corresponding to a residual quantization of charge. From the temperature and m...

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 کاملCoulomb blockade versus coherence in transport through a double junction
We construct a model describing current transport through a superconducting or normal conducting circuit consisting of two point contacts in series by extending a Green’s functions technique. In between the contacts is a mesoscopically large and bulklike island. The model can, in principle, handle contacts in all transmission regimes. Coherent interaction throughout the whole system is included...
