چکیده

It is shown that for two open quantum dots connected by a wire, “bound states in the continuum” of a single electron are formed at nearly periodic distances between the dots. This is due to Fabry-Pérot interference between quasi-bound states in each dot. The bound states are non-local, describing the electron trapped in both dots at the same time. Theoretical and numerical results show that trapped states exist even if the wire connecting the dots is relatively long.

Energy Levels of InGaAs/GaAs Quantum Dot Lasers with Different Sizes

In this paper, we have studied the strain, band-edge, and energy levels of cubic InGaAs quantum dots (QDs) surrounded by GaAs. It is shown that overall strain value is larger in InGaAs-GaAs interfaces, as well as in smaller QDs. Also, it is proved that conduction and valence band-edges and electron-hole levels are size dependent; larger QD sizes appeared to result in the lower recombination...

Energy states and exchange energy of coupled double quantum dot in a magnetic field

The ground state energies of two interacting electrons confined in a coupled double quantum dot (DQD) presented in a magnetic field has been calculated by solving the relative Hamiltonian using variational and exact diagonalization methods. The singlet-triplet transitions in the angular momentum and spin of the quantum dot ground state had been shown .We have studied the magnetic field versus c...

Unbound states in quantum heterostructures

We report in this review on the electronic continuum states of semiconductor Quantum Wells and Quantum Dots and highlight the decisive part played by the virtual bound states in the optical properties of these structures. The two particles continuum states of Quantum Dots control the deco-herence of the excited electron – hole states. The part played by Auger scattering in Quantum Dots is also ...

Resonances in quantum-dot transport.

Scattering resonances in ballistic conduction across a quantum dot in a weak magnetic field are investigated. Due to the special geometry considered, the resonances grow narrower with decreasing B, until at B = 0 they become bound states in the continuum. Whereas previously treated geometries exhibit at most one bound state with energy in the continuum, the number of such states in the present ...
