Excitonic structure in a quantum well under the tilted magnetic field
(AMER INST PHYSICS, 2000)
By using an appropriate coordinate transform we have calculated variationally the ground state exciton binding energy in the single square well under the tilted magnetic field. The dependence of the binding energy to the ...
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 ...
Nonlinear optical properties of triple delta-doped quantum wells: The impact of the applied external fields
(ELSEVIER GMBH, 2019)
In the present paper, we theoretically investigate the effect of applied external fields, such as electric, magnetic, and intense terahertz laser fields on the optical absorption and the relative refractive index change ...
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 ...
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 ...
