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 ... -
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 ... -
Broadband asymmetric quantum-well infrared photodetector in long-wavelength infrared range (LWIR)
(IEEE, 2007)A theoretical investigation of a GaAs-AlGaAs infrared detector consisting of three asymmetric quantum wells is presented. Each quantum well is sensitive to yield absorption and a photoresponse at peak wavelengths of 8 pro, ... -
Combined effects of intense laser field and applied electric field on exciton states in GaAs quantum wells: Transition from the single to double quantum well
(WILEY-V C H VERLAG GMBH, 2012)The effects of intense laser radiation on the exciton states in GaAs-Ga1xAlxAs quantum wells are studied with the inclusion of applied dc electric fields oriented along the growth direction of the system. The calculations ... -
Double quantum well electronic energy spectrum within a tilted magnetic field
(ACADEMIC PRESS LTD, 1999)The analytical solutions of the Schrodinger equation for a double quantum well structure (DQWS) subjected to an externally applied tilted magnetic field are obtained and the results are discussed. The dependency of the ... -
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. ... -
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 ...
