The electric field dependence of the photoionization cross-section of shallow donor impurities in quantum dots: Infinite and finite model
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2006)
Using a variational approach, we have calculated the photo-ionization cross-section of a shallow donor impurity in a quantum dot with finite and infinite potential barriers in the presence of an electric field as a function ...
Effects of an intense, high-frequency laser field on the binding energy of excitons confined in a GaInNAs/GaAs quantum well
(ELSEVIER SCIENCE BV, 2012)
The effects of an intense, high-frequency laser field linearly polarized along the growth direction on the binding energy of excitons confined in a GaInNAs/GaAs quantum well is computed for different nitrogen and indium ...
Spin-orbit interaction effects on the optical properties of quantum wires under the influence of in-plane magnetic fields
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2015)
In this work, we studied the effects of in-plane magnetic field and Rashba spin-orbit interaction on the intersubband optical absorption coefficients and changes in refractive index for transitions between the first two ...
Interband absorption and exciton binding energy in an inverse parabolic quantum well under the magnetic field
(ELSEVIER SCIENCE BV, 2007)
We have investigated the effects of the magnetic field which is applied perpendicular to the growth direction of the well on the interband absorption and on the binding energy of the excitons in an GaAs/Ga1-xAlxAs inverse ...
Optical properties of double quantum wires under the combined effect of spin-orbit interaction and in-plane magnetic field
