The binding energies of two electrons in a spherical quantum dot with square-well potential confinement are considered. The electron-electron interaction is included through a screened coulomb potential using the Richardson-Vinsome screening function applicable to GaAs. The finite barrier model lead

The binding energies of a hydrogenic donor in a GaAs spherical quantum dot in the Ga 12x Al x As matrix are presented assuming parabolic confinement. Effects of hydrostatic pressure and electric field are discussed on the results obtained using a variational method. Effects of the spatial variation
The binding energy of a shallow hydrogenic impurity in a spherical quantum dot under hydrostatic pressure with square well potential is calculated using a variational approach within the effective mass approximation. The effect of conduction band non-parabolicity on these energies is also estimated.
