چکیده

Abstract The triplet 2 3 S state of a 2-electron 2-dimensional quantum dot in magnetic field is studied via complementary perspective Schrodinger–Pauli theory. that the individual electron its equation motion or ‘Quantal Newtonian’ first law. According to law, each experiences an external and internal field, sum which vanishes. binding Lorentz fields. electron-interaction, kinetic, differential density, energy expressed integral virial form terms these quantal sources density; paramagnetic, diamagnetic, magnetization current densities; pair-correlation Fermi–Coulomb hole charge; single-particle density matrix are obtained, from them corresponding fields determined. shown satisfy

Effect 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...

The 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...
