Shallow donor impurity binding energy in the V-shaped quantum well under the crossed electric and magnetic fields
(ELSEVIER SCIENCE BV, 2005)
We have calculated variationally the ground state binding energy of a hydrogenic donor impurity in V-shaped quantum well (VQW) or full-graded GaAs/Ga1-xAlxAs quantum wells in the presence of crossed electric and magnetic ...
The effect of hydrostatic pressure on optical transitions in quantum-well wires
(ELSEVIER SCIENCE BV, 2004)
Using a variational approach, we have investigated mainly, the effect of the hydrostatic pressure, and the wire dimension on the interband optical absorption and the exciton binding energy in a quantum-well wire. We have ...
Subband structure and excitonic binding of graded GaAs/Ga1-xAlxAs quantum wells under an electric field
(ACADEMIC PRESS LTD, 1998)
The effects of an applied electric field on subband energies and excitonic binding for a graded GaAlAs quantum well are calculated variationally within the effective mass approximation. The very sensitive dependence of ...
