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 ...
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 ...
The magnetoexciton binding energy dependency on aluminium concentration in cylindrical quantum wires
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2009)
A calculation of the binding energy of an exciton confined in cylindrical quantum wires of GaAs surrounded by (Ga, Al) As in the presence of a uniform magnetic field is reported as a function of wire radius, potential ...
