Binding energies of shallow donor impurities in different shaped quantum wells under an applied electric field

Kasapoglu, E; Sari, H; Sokmen, I (ELSEVIER SCIENCE BV, 2003)

We present a variational method to compute the binding energies for a hydrogenic impurity located at the center of the finite parabolic (PQW), V-shaped (VQW or full graded well) and square (SQW) GaAs-Ga1-xAlxAs quantum ...
Effects of applied electromagnetic fields on the optical transitions in a V-shaped quantum well

Yesilgul, U.; Ungan, F.; Sakiroglu, S.; Kasapoglu, E.; Sari, H.; Sokmen, I. (ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2013)

In this study, the interband optical transitions and the binding energy of an exciton in a GaAs/Ga1-xAlxAs V-shaped quantum well (VQW) under the electric and magnetic fields are calculated. The calculations were performed ...
The linear and nonlinear intersubband optical absorption coefficients and refractive index changes in a V-shaped quantum well under the applied electric and magnetic fields

Yesilgul, U.; Ungan, F.; Kasapoglu, E.; Sari, H.; Sokmen, I. (ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011)

In this study, the changes in the optical absorption coefficients and the refractive index in a V-shaped quantum well have investigated theoretically. Within the effective mass approximation, the electronic structure of ...
