The control is the potential well absolute position. For two kinds of potential shape (periodic and box), we propose approximated solutions to the stead-state motion planing problem: steering in finite time the particle from an initial well position to a final well position, the initial and final particle energies being identical. This problem is a quantum analogue of the water tank problem, wh...

In this study, the effect of MQW structures adopting inorganic material (sodium fluoride) has been demonstrated. Brightness, current efficiency was significantly enhanced with a NaF/NPB MQW structure being inserted. The admittance spectroscopy was measured to explain the different mechanism of reducing hole between organic/organic inorganic/organic MQW

The calculation of the radiative lifetime of a localized exciton confined in a quantum we11 is performed for CdTe/(Cd.hln)Te structure where the quasi-free exciton magnetic polaron can be formed. There is shown that the polaron induced squeezing of the in-plkne esciton localization radius leads to the increase of the lifetime. The lifetime dependence on the quantum well width is found to be alt...
