Abstract:
A review of the ground state confinement energy term in the Brus equation for the bandgap energy of a spherically shaped semiconductor quantum dot was made within the framework of effective mass approximation. The Schrodinger wave equation for a spherical nanoparticle in an infinite spherical potential well was solved in spherical polar coordinate system. Physical reasons in contrast to mathematical expediency were considered and solution obtained. The result reveals that the shift in the confinement energy is less than that predicted by the Brus equation as was adopted in most literatures.

Abstract:
An atom located at the center of the constant spherical potential is adopted as a simple model for a quantum dot with impurity. We find that, under this model, the stability of the energy levels of a quantum dot with impurity can be controlled by adjusting either the size or the band gap of the quantum dot.

The effect of the central cell correction on the binding energies of shallow donors in a spherical GaAs-Ga 1-x Al x As quantum dot is studied. The effective-mass approximation within a variational scheme is adopted and central cell corrections are calculated by using a Coulomb potential modified with an adjustable parameter. For small values of the radius of the dot large corrections are obtained for the shallow donors studied.

Abstract:
The electrical properties of semiconductor systems of spherical GaAs / AlxGa1-xAs quantum dots of various dimensions, depending on the energy of the Fermi level and temperature, and the concentration of aluminum in the matrix, are investigated. Dependences of group velocity of electrons on the index of minisons were obtained. Reducing the CT radius, as well as increasing the aluminum concentration in the matrix, results in an increase in group velocity. The change in the sign of the group velocity of individual minisons is caused by the behavior of the isoenergetic surfaces of these minisons. The electrical conductivity is calculated, containing the contributions of the s- and three p-minisons for given parameters of the system, the maximum of which is near the center of the minisone. The increase in electrical conductivity is observed with a decrease in the CT radius and the aluminum concentration, as well as with the decrease of the GaAs / AlxGa1-xAs superlattice dimension. The temperature dependence of electrical conductivity for various parameters of such systems is also investigated.

Using a dielectric continuum approach, the optical vibration modes in a spherical core-shell quantum dots (QDs) imbedded in a host nonpolar material are studied. The dispersion relation and the corresponding electron–phonon interaction Hamiltonian are derived. The numerical calculations for the CdSe/ZnS system are performed. The results reveal that there are three branches frequencies of interface/surface optical phonon in the system. A detailed discussion of the combined effects of the spatial confinement and dielectric mismatch between the dot and the host medium is given.

CdSe semiconducting Quantum dots were prepared by a chemical method at a room temperature.

The absorption and photoluminescence spectra of the CdSe quantum dots were strongly shown blue shifted due to size quantization.

In this paper, electromagnetically induced transparency (EIT) is investigated in a GaAs spherical quantum dot (SQD) with central potential in presence of spherical metallic nanoparticle (SMNP). Solving the Schrödinger equation in effective mass, eigenfunctions and eigenvalues of SQD are obtained. By using the obtained eigenfunctions and eigenvalues, the susceptibility of SQD is found. In addition, dependence of EIT on radius of SQD and SMNP, distance between SMNP and SQD and Rabi and probe frequencies are investigated.

Abstract:
A theory of photoluminescence and Raman scattering in semiconductor quantum dots is developed, which relies on two key ingredients. First, it takes into account non-adiabaticity of the exciton-phonon system. Second, it includes a multimode dielectric model of LO-phonons and of the electron-phonon interaction in confined systems. Our approach is applied to calculate the optical spectra of several quantum-dot structures: ensembles of spherical CdSe, CdSe x S 1-x and PbS quantum dots, self-assembled InAs/GaAs and CdSe/ZnSe quantum dots, brick-shaped InAs/GaAs quantum dots created by local anodic oxidation using the atomic force microscope.

Abstract:
Herein, we report the synthesis of PbS Quantum Dots (QDs) with oleic acid as surfactant molecules by non coordinating solvent route. The particles are having better size tunability by varying temperature and time of reaction. These quantum dots are characterized by optical absorption, photoluminescence and transmission electron microscopy. The resulting colloids are highly stable, extremely small size, spherical in shape, monodisperse and strong band emission. The estimated particles sizes are in the range of 2 to 6 nm. The present method of synthesis of PbS quantum dots can be used to fabricate low cost electronic devices.
