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 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 ...
Shallow impurity binding energy in lateral parabolic confinement under an external magnetic field
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2008)
We have described the calculation of hydrogenic impurity binding energies in cylindrical GaAs-Ga(1-x)Al(x)As quantum well wires (QWWs) with lateral parabolic confinement in the presence of an axial magnetic field. The ...
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 ...
