    Ground state normalized binding energy of impurity in asymmetric quantum wells under hydrostatic pressure
    (Academic Press Ltd- Elsevier Science Ltd, 2016) Akbas, H.; Sucu, S.; Minez, S.; Dane, C.; Akankan, O.; Erdogan, I.
    We have studied and computed variationally the impurity energy, impurity energy turning points, and ground state normalized binding energy as functions of the impurity position for shallow impurity in asymmetric quantum wells under hydrostatic pressure. We found that the normalized binding energy significantly depends on the asymmetry of the well, besides depending on,the impurity position and hydrostatic pressure. Also, the dependence of the positive normalized binding energy on the pressure can be used to find out the degree of the asymmetry of the well or the impurity position in the well.

    The role of confinement and shape on the binding energy of an electron in a quantum dot
    (Elsevier Science Bv, 2008) Sucu, S.; Mese, A. I.; Okan, S. E.
    The impurity ground state binding energy in cubic and cylindrical GaAs/AlAs quantum dots has been calculated using a variational procedure within the effective mass approximation. We exploit the impurity ground state energy under an external electric field strongly affected by the anisotropy of the quantum dots more than their shapes. (C) 2008 Elsevier B.V.

    Self-polarization of a donor impurity for the first excited state in an Ga1-xAlxAs/GaAs quantum well
    (Indian Assoc Cultivation Science, 2021) Sucu, S.; Minez, S.; Erdogan, I
    In this study, self-polarization (SP) for the first excited state in the finite quantum well is presented by taking into account the hydrostatic pressure and the external electric field. We calculated the SP of the first excited state by using the variational method under the effective mass approximation. These calculations were made for different values of the quantum well-width, hydrostatic pressure, external electric field and impurity positions. Our results indicate that the self-polarization of the first excited state in finite quantum well depends remarkably on the hydrostatic pressure, external electric field strength and impurity position.
