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 ...
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 ...
