Photoionization cross-section and binding energy of shallow donor impurities in Ga1-xInxNyAs1-y/GaAs quantum wires
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
We have investigated the effects of the nitrogen and indium concentrations on the photoionization crosssection and binding energy of shallow donor impurities in Ga1-xInxNyAs1-y/GaAs quantum wires. The numerical calculations ...
Magnetic-field effect on the diamagnetic susceptibility of hydrogenic impurities in quantum well-wires
(ELSEVIER SCIENCE BV, 2009)
We have studied the magnetic field effects on the diamagnetic susceptibility and binding energy of a hydrogenic impurity in a quantum well-wire by taking into account spatially dependent screening. Using the effective-mass ...
The effects of temperature and hydrostatic pressure on the photoionization cross-section and binding energy of shallow donor impurities in quantum dots
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2010)
Using a variational approach we have calculated the hydrostatic pressure and temperature effects on the donor impurity related photoionization cross-section and impurity binding in GaAs/GaAlAs quantum dots Our calculations ...
The effects of the magnetic field and dielectric screening on the diamagnetic susceptibility of a donor in a quantum well with anisotropic effective mass
(ELSEVIER SCIENCE BV, 2010)
The diamagnetic susceptibility and the binding energy of a hydrogenic donor in a quantum well with different mass anisotropy parameters gamma=m(perpendicular to)/m(parallel to) are investigated in the presence of a magnetic ...
Intense laser effects on donor impurity in a cylindrical single and vertically coupled quantum dots under combined effects of hydrostatic pressure and applied electric field
(ELSEVIER SCIENCE BV, 2010)
Using the effective mass and parabolic band approximations and a variational procedure we have calculated the combined effects of intense laser radiation, hydrostatic pressure, and applied electric field on shallow-donor ...
