Investigation of Optical Properties of Quantum Dots in Presence of Magnetic, Electrical Fields
Tehran, Iran | Posted on June 10th, 2015Results of the research have applications in the designing and production of optoelectronic devices.
In the past decade, significant progress has been made in the methods to produce semi-conductive nanostructures, and in administration of the related optical phenomena. Optical properties of semi-conductive nanostructures include a wide range of potential applications in the production of electronic devices.
This research studies the optical properties of quantum dots semi-conductive nanostructures, and it investigates the effect of size and type of quantum dot on the properties.
In this research, the effect of simultaneous presence of external electrical and magnetic fields and the interaction between electron and pores on the system energy levels were studied in a spherical quantum dot. Then, optical alignment factor and the effect of electron-pore interaction were calculated by using quantum mechanics laws and density matrices. Finally, the effect of type and size were studied too.
Results of modeling and calculation showed that as the size of quantum dot increases, the energy of electron-pore decreases. In addition, the alignment factor decreases as quantum limitation increases as a non-linear agent. However, electrical and magnetic fields act opposite to the extent that they neutralize each other's effects.
Results of the research have been published in Optik, vol. 126, issue 23, 2014, pp. 6926-6929.
