The size-dependent band gap of semiconductor quantum dots is a well-known and widely
studied quantum confinement effect. In order to understand the size-dependent band gap …

The electronic structure of a spherical quantum dot with parabolic confinement that contains
a hydrogenic impurity and is subjected to a DC electric field is studied. In our calculations we …

We study the effects of excitons in nonlinear optical rectification in one-dimensional
semiparabolic quantum dots. We consider the cases that the electron and the hole are …

The donor binding energies associated with the ground state and a few excited states are
computed as a function of the dot size and the impurity position within two-and three …

Using the potential morphing method within the finite depth square-well effective mass
approximation, we calculate the exciton energy of narrow band gap colloidal PbS, PbSe …

We study the effect of an external electric field on an exciton bound to an ionized donor (D+,

The binding energies of a hydrogenic donor in a GaN/AlGaN quantum dot are calculated in
the influence of magnetic field. The calculations are carried out using the single-band …

The binding energy of a biexciton confined in InAs nanorods is calculated using the potential
morphing method. Once the system under investigation is in a crossover state, the spectral …

Combined effects of magnetic and electric fields on the confined exciton in an InAs 1− x P
