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 ...
The triple Si delta-doped GaAs structure
(SPRINGER, 2005)
For the uniform donor distribution we have theoretically investigated the influence of the separation between the adjacent two doping layers on the electronic structure of the triple Si delta-doped GaAs, at T = 0 K. To ...
Intersubband electron transition across a staircase potential containing quantum wells: light emission
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2005)
We present a theoretical investigation of a novel staircase-like light emitter based on the GaAs/GaxAl1-xAs material system. The emission wavelength is around 12 mum. The device operation is based on the intersubband ...
Subband structure and band bending in symmetric modulation-doped double quantum wells
(EDP SCIENCES S A, 2005)
We have calculated the subband structure and confinement potential of modulation-doped Ga1-xAlxAs-GaAs symmetric double quantum wells a function of the doping concentration. Electronic properties of this structure are ...
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 ...
Electric field and intense laser field effects on the intersubband optical absorption in a graded quantum well
(IOP PUBLISHING LTD, 2005)
The laser field dependence of the intersubband optical absorption in a graded quantum well (GQW), under an applied electric field is calculated in the effective mass approximation. We have theoretically shown that, in the ...
The effects of hydrostatic pressure and applied electric field on shallow donor impurities in GaAs/GaAlAs graded quantum well
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2005)
Using a variational approach, we have investigated the effects of the hydrostatic pressure, the well dimension, impurity position and electric field direction on the binding energy of shallow donor impurities in GaAs/GaAlAs ...
Intersubband transitions in quantum wells under intense laser field
(SPRINGER, 2005)
An intense laser field effect on the intersubband transitions in quantum wells is theoretically investigated within the framework of the effective-mass approximation. Results obtained show that intersubbband optical ...
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. ...
