Geometrical effects on shallow donor impurities in quantum wires
(ELSEVIER SCIENCE BV, 2003)
We have studied theoretically the impurity binding energy for wires of different shapes (V-shaped quantum wire (V-QWR) and rectangular wire) with a variational procedure without using any coordinate transformation. The ...
Shallow donors in the triple-graded quantum well under the hydrostatic pressure and external fields
(ELSEVIER SCIENCE BV, 2006)
The binding energy of the donor in the triple-graded GaAs-(Ga,Al)As quantum well under the hydrostatic pressure, electric and magnetic fields are calculated by using a variational approach. The results have been obtained ...
Optical properties of excitons in quantum well wires under the magnetic field
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2003)
The binding energy of excitons in quantum well wires of GaAs surrounded by Ga1-xAlxAs was calculated in an effective mass approximation with the use of the variational approach. Results obtained show that the exciton binding ...
The effect of hydrostatic pressure on the photoionization cross-section and binding energy of impurities in quantum-well wire under the electric field
(ELSEVIER SCIENCE BV, 2005)
Using a variational approach, we have calculated the hydrostatic pressure and electric field effects on the donor-impurity related photoionization cross-section and impurity binding energy in GaAs/GaAlAs quantum well-wires. ...
Binding energy of hydrogenic impurities in a quantum well under the tilted magnetic field
(PERGAMON-ELSEVIER SCIENCE LTD, 2003)
This paper treats theoretically the angle dependence of the ground state binding energy of a shallow donor impurity in semiconductor quantum-well systems on the tilted magnetic field. By making an appropriate coordinate ...
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 ...
Magnetic field and intense laser radiation effects on the interband transitions in quantum well wires
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2004)
Magnetic field and intense laser radiation effects on the exciton binding energy and interband optical transitions in quantum well wires is calculated using a variational method and in the effective mass approximation. The ...
Influence of an applied electric field on the electronic properties of Si delta-doped GaAs
(E D P SCIENCES, 2003)
We have theoretically studied the electronic structure of Si delta-doped GaAs inserted into an infinite quantum well as dependent on the applied electric field. For the uniform distribution we have investigated the influence ...

(IOP PUBLISHING LTD, 1997)
The: analytical solutions of the Schrodinger equation for a square well system subjected to an externally applied electric field in the growth direction and an externally applied tilted magnetic field are obtained and the ...
The photoionization cross-section and binding energy of impurities in quantum wires: Effects of the electric and magnetic field
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2004)
Using a variational approach, we have calculated the impurity position dependence of the photoionizaton cross-section and the binding energy for a hydrogenic donor impurity in a quantum well wire in the presence of the ...
