A Coulomb-blockade thermometer (CBT) provides calibration-free measurement of low temperatures, even in strong magnetic fields---but slowly. standard conductance with a CBT takes typically minutes, which is useless applications where relatively fast changes temperature are monitored. Besides, slow prone to drifts, and low-frequency noise. The authors solve this issue by hooking sensor into radi...

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...

Coherent electronic transport in single-molecule junctions is investigated in the Coulomb blockade regime. Both the transmission phase and probability are calculated for junctions with various contact symmetries. A dramatic suppression of the Coulomb blockade peaks is predicted for junctions where multiple atomic orbitals of the molecule couple to a single electrode although the charging steps ...

The charge stored on a capacitor is not quantized: it consists of polarization charges generated by displacing the electron gas with respect to the positive lattice ions and can take arbitrary magnitudes. The charge transfer across a tunnel junction, however, is quantized in units of the electron charge (singleelectron tunneling), and may be suppressed due to the Coulomb interaction (Coulomb bl...

In the resonant tunnelling diode we have treated electrons as non interacting particles. We have discussed their wave nature, which led to quantized energy states in small and coherent cavities. Qualitatively this is due to the requirement that an integer number of Fermi wavelengths has to fit between the barriers. Here we begin in the opposite limit by neglecting space quantization effects in ...

We review the quantum interference effects in a system of interacting electrons confined to a quantum dot. The review starts with a description of an isolated quantum dot. We discuss the Random Matrix theory (RMT) of the one-electron states in the dot, present the universal form of the interaction Hamiltonian compatible with the RMT, and derive the leading corrections to the universal interacti...
