ABSTRACT
In the InAs/In1-xAlxAs spherical quantum dot, the variation of the intradonor transation and normalized intradonor transition energies are calculated using the variational method under the effective mass approximation. It has been observed that when the quantum dot radius increases, the intradonor transition energy decreases, whereas the normalized intradonor transition energy increases when the impurity is located near the center of the quantum dot and remains constant when it is near the edge. In addition, we determined that when the aluminum concentration increases, the intradonor transition energy increases while the normalized intradonor transition energy decreases. However, when the position of the impurity changes from the center of the quantum dot to the edge, it is observed that the intradonor transition energy first decreases and then increases again after the minimum value, while the normalized intradonor transition energy decreases and does not change even if the aluminum concentration is increased after the position of the impurity where the intradonor transition energy is minimum. To our knowledge, this study has been the first to calculate the normalized intradonor transition energy for the InAs/In1-xAlxAs structure for different aluminum concentrations.
