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 ...
Photoionization cross-section and binding energy of donor impurities in GaAs, Ge and Si quantum wires with infinite barriers
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2009)
Within the effective-mass approximation, we have investigated the binding energies of donor impurities as a function of the wire dimensions and the photoionization cross-section for a hydrogenic donor impurity placed on ...
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 ...
