Abstract

sources, among which, semiconductor quantum dots are particularly attractive thereby quantum dots embedded in semi-conductor nanowires. Quantum dots with different energy levels and wave functions which leeds the absorption and emission of different photons, can have various applications. In this article, firstly, the electronic properties of two indium arsenide quantum dots located symmetrically at the center of galium arsenide quantum wire were investigated. This is done by numerically solving the Schrodinger equation, using Comsol software and the finite element method. The energy eigenvalues, and eigenfunctions were calculated and compared with other similar works. The main research here is solving and using the self-consistent Poisson-Schrödinger equation for the various nanostructures. Then, by using the self-consistent Poisson-Schrödinger equation, the effect of impurities on the electronic properties of the quantum nano wire and the structure of the two quantum spheres inside the quantum wire has been obtained. These results are compared with the results of solving the Schrödinger equation in limiting conditions. The obtained results indicate that the effect of impurities are significant, while the effect of temperature from low temperatures to ambient temperature is insignificant, but the effect of changes in internal radii and the amount of contaminated impurity on the electronic properties of the nanostructure is significant and can be calculated.
