Journal of Taibah University for Science, 2017 The combined effects of pressure and temperature on the energy levels of a parabolic GaAs quantum dot under a magnetic field have been studied. The exact diagonalization method was used to solve the two-electron quantum dot Hamiltonian and to obtain the ...

Formation InAs Quantum Dots in a Matrix GaAs in Kinetic Mode for CVD-method [PDF]
Журнал нано- та електронної фізики, 2017 We present the results of theoretical study for the kinetic mode of quantum dot formation in the InAs / GaAs system. The theory is valid at the kinetic stage of quantum dot formation, when the island ensemble remains dilute and thus noninteracting.

Experimental realization of the one qubit Deutsch-Jozsa algorithm in a quantum dot
, 2004 We perform quantum interference experiments on a single self-assembled semiconductor quantum dot. The presence or absence of a single exciton in the dot provides a qubit that we control with femtosecond time resolution.

An optical modulator based on a single strongly coupled quantum dot - cavity system in a p-i-n junction [PDF]
, 2009 We demonstrate an optical modulator based on a single quantum dot strongly coupled to a photonic crystal cavity. A vertical p-i-n junction is used to tune the quantum dot and thereby modulate the cavity transmission, with a measured instrument-limited ...

Si-Doped InAs/GaAs Quantum Dot Solar Cell with Alas Cap Layers
E3S Web of Conferences, 2017 In this work, the effect of Si doping on InAs/GaAs quantum dot solar cells with AlAs cap layers is studied. The AlAs cap layers suppress the formation of the wetting layer during quantum dot growth.

Correlation-induced resonances and population switching in a quantum dot coulomb valley
, 2007 Strong correlation effects on electron transport through a spinless quantum dot are considered. When two single-particle levels in the quantum dot are degenerate, a conserved pseudospin degree of freedom appears for general tunneling matrix elements ...
