The effect of hydrostatic pressure on binding energy of impurity states in spherical quantum dots
TL;DR: In this article, the binding energy of shallow hydrogenic impurities in spherical quantum dots in the influence of pressure is calculated using a variational approach within the effective mass approximation, and the results show that the impurity binding energy increases with the reduction in dot sizes for a given pressure.

Optical properties of a hydrogenic impurity in a confined Zn1−xCdxSe/ZnSe spherical quantum dot
TL;DR: In this paper, the effect of longitudinal optical phonon field on the ground state and low lying-excited state energies of a hydrogenic impurity in a Zn 1− x Cd x Se/ZnSe strained quantum dot is investigated for various Cd content using the Aldrich-Bajaj effective potential.

Simultaneous effects of pressure and temperature on donors in a GaAlAs/GaAs quantum well
TL;DR: In this paper, the ground state and excited state energies of a hydrogenic donor in a quantum well are computed in the presence of pressure and temperature, and the binding energies are worked out for GaAs/Ga1-xAlxAs structures as a function of well size.

Polarizabilities of shallow donors in spherical quantum dots with parabolic confinement
TL;DR: The binding energy and impurity polarizability of hydrogen donors in a spherical quantum dot of Cd 1 − x in Mn x in Te /Cd 1− x out Mn x out Te structure are presented assuming parabolic confinement.
