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 ...
Binding energy of hydrogenic impurities in a quantum well under the tilted magnetic field
(PERGAMON-ELSEVIER SCIENCE LTD, 2003)
This paper treats theoretically the angle dependence of the ground state binding energy of a shallow donor impurity in semiconductor quantum-well systems on the tilted magnetic field. By making an appropriate coordinate ...
The effect of an intense laser field on magneto donors in semiconductors
(ELSEVIER SCIENCE BV, 2003)
The laser-field dependence of the binding energy of shallow-donor impurities in graded, and square quantum wells under the external magnetic field is calculated by a variational method and in the effective mass approximation. ...
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 ...
