Effect of hydrostatic pressure on interband transitions in coupled quantum wires
(IOP PUBLISHING LTD, 2007)
We calculate the exciton binding energy and interband optical absorption in a rectangular coupled quantum wire under the hydrostatic pressure in the effective-mass approximation, using the variational approach. It is found ...
The polarizability and the photoionization cross-section under the external fields for donor impurities in quantum well-wire
(WILEY-V C H VERLAG GMBH, 2007)
In this study, we have calculated the donor impurity binding energy, donor impurity related photoionization cross-section and polarizability in symmetric GaAs/Ga1-xAlxAs quantum well-wire as a function of the impurity ...
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 ...
Binding energy of impurity states in an inverse parabolic quantum well under magnetic field
(ELSEVIER SCIENCE BV, 2007)
We have investigated the effects of the magnetic field which is directed perpendicular to the well on the binding energy of the hydrogenic impurities in an inverse parabolic quantum well (IPQW) with different widths as ...
Density of impurity states of hydrogenic impurities in an inverse parabolic quantum well under the magnetic field
(ELSEVIER SCIENCE BV, 2007)
We investigated the effects of the magnetic field on the density of impurity states in a GaAs/GaAlAs inverse parabolic quantum well (lPQW) for different Al concentrations at the well center. The calculations were performed ...
