Tilted magnetic field effect on the subbands of a GaAlAs diode with a GaAs quantum well
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2003)
We have calculated the subbands in the GaAs quantum well at the n-side of the junction in a Ga1-xAlxAs diode. We show that the density of carriers confined in the quantum well increases by the increasing magnetic field ...
Binding energy of excitons in symmetric and asymmetric coupled double quantum wells in a uniform magnetic field
(IOP PUBLISHING LTD, 2000)
The binding energy of excitons in symmetric and asymmetric coupled double GaAs/Ga1-xAlxAs quantum wells is calculated by using a variational approach. The results have been obtained in the presence of a uniform magnetic ...
Electric field dependence of the excitonic properties in graded double quantum wells
(IOP PUBLISHING LTD, 1999)
A quasi-bound state approximation is used to obtain the electric field dependence of the eigenvalues, eigenfunctions, electron-hole overlap integrals and excitonic binding energies for coupled, graded double quantum wells ...
An alternative method for the exact calculation of Wannier-Stark localization in superlattices
(ACADEMIC PRESS LTD, 2001)
We present an alternative method for the exact calculations of the Wannier-Stark (WS) localization in a long periodic potential corresponding to a (50 Angstrom /30 Angstrom) GaAs/Ga0.7Al0.3As superlattice. We show that the ...
Intense field effects on shallow donor impurities in graded quantum wells
(IOP PUBLISHING LTD, 2003)
Using a variational method and within the effective mass approximation, we calculate the laser-field dependence of binding energy and the polarizability of shallow-donor impurities in graded quantum wells under an external ...
