Intersubband optical absorption in quantum wells under applied electric and intense laser fields
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2004)
Within the framework of the effective mass approximation, we have theoretically investigated the linear intersubband optical absorption in a quantum well under external electric and intense laser field. Results obtained ...
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 ...
