Intersubband optical absorption in quantum wells under applied electric and intense laser fields
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2004)
Within the framework of the effective mass approximation, we have theoretically investigated the linear intersubband optical absorption in a quantum well under external electric and intense laser field. Results obtained ...
Effects of crossed electric and magnetic fields on shallow donor impurity binding energy in a parabolic quantum well
(IOP PUBLISHING LTD, 2004)
We have calculated variationally the ground state binding energy of a hydrogenic donor impurity in a parabolic quantum well in the presence of crossed electric and magnetic fields. These homogeneous crossed fields are such ...
Shallow donor impurities in different shaped double quantum wells under the electric field
(WILEY-V C H VERLAG GMBH, 2004)
The binding energy of the donor impurity in double triangle quantum well (DTQW), double graded (DGQW) and double square (DSQW) GaAs-(Ga,Al)As quantum wells under the electric field is calculated by using a variational ...
Intersubband optical absorption in Si delta-doped GaAs for the donor distribution and thickness as dependent on the applied electric field
(E D P SCIENCES, 2004)
We have theoretically investigated the intersubband transition for different doping concentrations and thickness in Si delta-doped GaAs with an applied electric field. The electronic properties such as the delta-potential ...
Photoionization of donor impurities in quantum wires in a magnetic field
(IOP PUBLISHING LTD, 2004)
Using a variational approach, we have calculated the impurity position dependence of the photoionization cross-section and the binding energy of a hydrogenic donor impurity in a quantum well wire in the presence of the ...
Effect of crossed electric and magnetic fields on donor impurity binding energy
(SPRINGER-VERLAG, 2004)
By using an appropriate coordinate transformation, we have calculated variationally the ground state binding energy of a hydrogenic donor impurity in a quantum well in the presence of crossed electric and magnetic fields ...
Barrier thickness dependence of optical absorption of excitons in GaAs coupled quantum wire
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2004)
We have calculated the binding energy of excitons, and the interband optical absorption in rectangular coupled quantum-well wires of GaAs surrounded by Ga1-chiAlchiAs in effective-mass approximation, using the variational ...
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 ...
The electric field dependence of a donor impurity in graded GaAs quantum wires
(SPRINGER HEIDELBERG, 2004)
The effect of the electric field on the binding energy of the ground state of a shallow donor impurity in a graded GaAs quantum-well wire (GQWW) was investigated. The electric field was applied parallel to the symmetry ...
Intersubband transitions of Si delta-doped GaAs layer for different donor distribution models
(IOP PUBLISHING LTD, 2004)
For different donor distribution types we theoretically investigate the intersubband transitions of single Si delta-doped GaAs structure as dependent on the applied electric held. The diffusion of donor impurities is taken ...
