Ground state energy of excitons in quantum dot treated variationally via Hylleraas-like wavefunction
(IOP PUBLISHING LTD, 2009)
In this work, the effects of quantum confinement on the ground state energy of a correlated electron-hole pair in a spherical and in a disc-like quantum dot have been investigated as a function of quantum dot size. Under ...
The effects of the intense laser field on donor impurities in a cylindrical GaxIn1-xNyAs1-y/GaAs quantum dot under the electric field
(ELSEVIER SCIENCE BV, 2011)
For different nitrogen and indium concentrations, intense laser field (ILF) effect on donor impurity binding energy in a cylindrical GaxIn1-xNyAs1-y/GaAs quantum dot (QD) has been studied. Results show that ILF creates an ...
Intense laser field effect on impurity states in a semiconductor quantum well: transition from the single to double quantum well potential
(SPRINGER, 2011)
In this work are studied the intense laser effects on the impurity states in GaAs-Ga1- (x) Al (x) As quantum wells under applied electric and magnetic fields. The electric field is taken oriented along the growth direction ...
Tunable long-wavelength broad band asymmetric quantum well infrared photodetector
(IOP PUBLISHING LTD, 2007)
We present a theoretical investigation of a GaAs/AlGaAs infrared detector consisting of three asymmetric quantum wells. Each well is designed to yield absorption and a photoresponse at peak wavelengths of 8.2 mu m, 9.5 mu ...
Linear and nonlinear optical properties in a semiconductor quantum well under intense laser radiation: Effects of applied electromagnetic fields
