Properties of the second-order nonlinear optical susceptibility x „2... in asymmetric undoped AlGaAs/InGaAs double quantum wells
The second-order nonlinear optical susceptibility x (2) for second-harmonic generation is calculated for the 11H transition of a graded double quantum well ~DQW! structure of undoped GaAs/AlxGa12xAs. These results are compared with the single quantum well ~QW!. Our results show that the values of x (2) have optimal magnitudes dependent on the width, depth and separation between the QWs in a DQW...
متن کاملPhoto-Induced Spin Dynamics in Semiconductor Quantum Wells
We experimentally investigate the dynamics of spins in GaAs quantum wells under applied electric bias by photoluminescence (PL) measurements excited with circularly polarized light. The bias-dependent circular polarization of PL (P(PL)) with and without magnetic field is studied. The P(PL) without magnetic field is found to be decayed with an enhancement of increasing the strength of the negati...
متن کاملDegenerate four waves mixing in multilayer nanoshell
We will present a detailed investigation of intersubband transitions process in core-multi shells quantum dots. The confined wave functions and eigenenergies of electrons in quantum dots have been calculated under the effective-mass approximation by solving a three-dimensional Schrodinger equation. Excellent dependence is found between size effects, time relaxation and degenerate four wave mixi...

متن کاملSpin-Exchange Interaction in ZnO-based Quantum Wells
Wurtzitic ZnO/(Zn,Mg)O quantum wells grown along the (0001) direction permit unprecedented tunability of the short-range spin exchange interaction. In the context of large exciton binding energies and electron-hole exchange interaction in ZnO, this tunability results from the competition between quantum confinement and giant quantum confined Stark effect. By using time-resolved photoluminescenc...
