Improvement in intersubband optical absorption and the effects of device parameter variations in quantum wells with an applied electric field
(ACADEMIC PRESS LTD, 1999)
The intersubband optical absorption in symmetric and asymmetric, single and coupled, double GaAs/Ga1-xAlxAs quantum wells is calculated. The results have been obtained in the presence of a uniform electric field as a ...
Shallow donors in a triple graded quantum well under electric and magnetic field
(ELSEVIER SCIENCE BV, 2003)
The binding energy of the donor impurity in triple graded GaAs-(Ga,Al)As quantum wells is calculated by using a variational approach. The results have been obtained in the presence of a uniform magnetic and electric field ...
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 ...
Intersubband transitions in coupled triple-graded quantum wells under an electric field
(WILEY-V C H VERLAG GMBH, 2005)
The intersubband transitions were calculated in three different shaped triple-graded quantum wells. The investigation involved changing the depth of the central well potential under an electric field applied parallel to ...
Shallow donor impurities in different shaped double quantum wells under the hydrostatic pressure and applied electric field
(ELSEVIER SCIENCE BV, 2005)
The combined electric field and hydrostatic pressure effects on 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 ...
Optical transitions in quantum well wires under intense laser radiation
(ELSEVIER SCIENCE BV, 2003)
The influence of a laser-field on the exciton binding energy and interband optical transitions in quantum-well wires is calculated by using a variational method and in the effective mass approximation. We conclude that in ...
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 ...
Binding energy of excitons in symmetric and asymmetric coupled double quantum wells in a uniform magnetic field
(IOP PUBLISHING LTD, 2000)
The binding energy of excitons in symmetric and asymmetric coupled double GaAs/Ga1-xAlxAs quantum wells is calculated by using a variational approach. The results have been obtained in the presence of a uniform magnetic ...
