Electron transport through double quantum dots
Electron transport experiments on two lateral quantum dots coupled in series are reviewed. An introduction to the charge stability diagram is given in terms of the electrochemical potentials of both dots. Resonant tunneling experiments show that the double dot geometry allows for an accurate determination of the intrinsic lifetime of discrete energy states in quantum dots. The evolution of disc...
متن کاملPhonons and Phonon Confinement in Transport through Double Quantum Dots
We calculate the electron–phonon interaction coefficients for surface acoustic waves and for phonons in free standing quantum wells. These are used to derive the inelastic current through a double quantum dot caused by spontaneous emission of phonons. For the case of the free standing structure (phonon cavity), we predict a staircase–like inelastic current superimposed by van Hove singularities...
متن کاملElectron Transport through Double Quantum Dots with Interdot Coulomb Repulsion
Electron transport through a system of two quantum dots connected in series is studied theoretically with the use of non-equilibrium Green function formalism based on the equation of motion method. Each dot is described by the one-level Anderson Hamiltonian and interdot Coulomb interactions in the form of the Hubbard-like term are taken into account. The electric current and occupation numbers ...
متن کاملIsospin Blockade in Transport through Vertical Double Quantum Dots
We study the spectrum and the transport properties of two identical, vertically coupled quantum dots in a perpendicular magnetic field. We find correlation-induced energy crossings in a magnetic field sweep between states differing only in the vertical degree of freedom. Considering the influence of a slight asymmetry between the dots caused by the applied source-drain voltage in vertical trans...
متن کاملRenormalization group study of capacitively coupled double quantum dots
The numerical renormalization group is employed to study a double quantum (DQD) dot system consisting of two equivalent single-level dots, each coupled to its own lead and with a mutual capacitive coupling embodied in an interdot interaction U , in addition to the intradot Coulomb interaction U . We focus on the regime with two electrons on the DQD, and the evolution of the system on increasing...
