Within the effective-mass approximation and with two-parameter variational procedure we have calculated the effect of spatial electric field and ratios of dot edge lengths(c/a) on the electron sub-band energy and the polarization of an electron in the tetragonal GaAs/AlAs quantum dot. It is found th
The electron sub-band energy of a cubic GaAs/AlAs quantum dot under an applied spatial electric field is theoretically investigated within a variational scheme. In this case, we show that the electron sub-band energy E decreases with spatial electric field strength F and increases or decreases depen
A variational approach is used to study the ground state of a bound polaron in a spherical quantum dot under an external electric field. The binding energy of the hydrogenic impurity state is calculated by taking the interaction of an electron with both the confined longitudinal optical phonons and
