With the size of plasmonic devices entering into the nanoscale region, the impact of quantum physics needs to be considered. In the past, the quantum size effect on linear material properties has been studied extensively. However, the nonlinear aspects have not been explored much so far. On the other hand, much effort has been put into the field of integrated nonlinear optics and a medium with ...
the combined effect of hydrostatic pressure and temperature on correlation energy in a triplet state of two electron spherical quantum dot with square well potential is computed. the result is presented taking gaas dot as an example. our result shows the correlation energies are i)negative in the triplet state contrast to the singlet state ii) it increases with increase in pressure iii)further...
chemical precipitation method was used in order to synthesize cdse:ag quantum dots (2-3 nm). their physical properties and characteristics were assessed by x-ray diffraction, ultra violet-visible spectrophotometer and tem (transmission electron microscope) and it was shown that the obtained cdse:ag quantum dots are cubic with high-quality. antibacterial effects of cdse:ag nanoparticles against ...
The purpose of this study is to investigate the relationship between managers' quantum skills and to improve the decision-making system with an emphasis on the mediating role of policy-making. The research method was descriptive-correlational in terms of practical purpose and in terms of data collection. The statistical population included all members of the faculty of Mazandaran Azad Un...

The dynamic of a charged quantum particle in a system of arrays of quantum well in tight-binding model, under the effect an external field, in one and two dimension, is studied by algebraic approach. The persistent (quantum confinement) and transmission (quantum teleportaion) probabilities of this quantum particle in terms of infinite-variable Bessel functions is calculated and the results i...
In this paper, the snap-through buckling of an initially curved microbeam subject to an electrostatic force, accounting for fringing field effect, is investigated. The general governing equations of the curved microbeam are developed using Euler-Bernoulli beam theory and used to develop a new criterion for the snap-through buckling of that beam. The size effect of the microbeam is accounted for...
in this research, the effect of the first order magnetic field on the ground-state of a centered hydrogenic donor impurity in a gaas/alas spherical quantum dot has been calculated. the perturbation method has been used within the framework of effective mass approximation for these calculations. overall, the analysis shows that a proper choice of quantum dot radius and magnetic field can signifi...
