Exciton absorption in quantum-well wires under the electric field
(ELSEVIER SCIENCE BV, 2003)
The binding energy of excitons, and interband optical absorption in quantum-well wires of GaAs surrounded by Ga1-xAlxAs is calculated in effective-mass approximation, using a variational approach. Results obtained show ...
Binding energies of shallow donor impurities in different shaped quantum wells under an applied electric field
(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 ...
Hydrogenic impurities in graded GaAs-(Ga,Al)As quantum-well wires in an electric field
(ELSEVIER SCIENCE BV, 2002)
The electric field dependence of polarizability and binding energy of shallow-donor impurities in graded quantum-well wires is calculated by a variational method and in the effective-mass approximation. We have considered ...
Subband structure and excitonic binding of graded GaAs/Ga1-xAlxAs quantum wells under an electric field
(ACADEMIC PRESS LTD, 1998)
The effects of an applied electric field on subband energies and excitonic binding for a graded GaAlAs quantum well are calculated variationally within the effective mass approximation. The very sensitive dependence of ...
