چکیده
Abstract The ground state energy of a helium atom inside spherical multilayer quantum dot as function the atomic impurity location has been calculated. is modeled by core/shell/well/shell structure using parabolic confinement. Configuration Interaction method and Diffusion Monte Carlo have used to solve Schrödinger equation. Results obtained showed that lowest configuration depends on size different layers agreement between results indicates approach here would be suitable compute excited states this system.

Binding energy of an off-center shallow donor D− in a spherical quantum dot
The binding energy of a negatively charged hydrogenic impurity with onand offcenter position in a spherical Gaussian quantum dot was calculated with the configuraction interaction method. Our calculations show that Eb is always positive for on-center impurities with a maximum near to the radius for one-electron stability of the potential well Rc. For off-center positions the binding energy can ...
متن کاملQuantization of electromagnetic fields in the presence of a spherical semiconductor quantum dot and spontaneous decay of an excited atom doped in this nanostructure
In this paper we consider electromagnetic field quantization in the presence of a dispersive and absorbing semiconductor quantum dot. By using macroscopic approach and Green's function method, quantization of electromagnetic field is investigated. Interaction of a two-level atom , which is doped in a semiconductor quantum dot, with the quantized field is considered and its spontaneous emission ...
متن کاملQuantum current modeling in nano-transistors with a quantum dot
Carbon quantum dots (CQDs) serve as a new class of ‘zero dimensional’ nanomaterial’s in thecarbon class with sizes below 10 nm. As light emitting nanocrystals, QDs are assembled from semiconductormaterials, from the elements in the periodic groups of II-VI, III-V or IV-VI, mainly thanks to impacts of quantum confinement QDs have unique optical properties such as brighter, highly pho...
متن کاملEffect of Temperature and Pressure on Correlation Energy in a Triplet State of a Two Electron Spherical Quantum Dot
The combined effect of hydrostatic pressure and temperature on correlation energy in a triplet state of two electron spherical quantum dot with square well potential is computed. The result is presented taking GaAs dot as an example. Our result shows the correlation energies are i)negative in the triplet state contrast to the singlet state ii) it increases with increase in pressure iii)further...
متن کاملThe effect of first order magnetic field in a GaAs/AlAs spherical quantum dot with hydrogenic impurity
In this research, the effect of the first order magnetic field on the ground-state of a centered hydrogenic donor impurity in a GaAs/AlAs spherical quantum dot has been calculated. The perturbation method has been used within the framework of effective mass approximation for these calculations. Overall, the analysis shows that a proper choice of quantum dot radius and magnetic field can signifi...
