Abstract

One of the IV-VI material systems that have shown promising growth and sustainability in optoelectronic applications is PbSrSe quantum dot structure (QDs) material. However, the material system belongs to the lead salt semiconductor group and has a constant energy surface with prolate ellipsoids of revolution, as well as a strongly nonparabolic energy band. In this study, the particle in a box model based on the effective mass approximation is used to theoretically investigate quantum confinement in PbSrSe spherical semiconductor quantum dots. For the first four excited states explored, it is found that the transition energies of   quantum dot depends on the quantum dot size.
