The effect of electromagnetic perturbation on the optical properties of (III Mn)V diluted magnetic semiconductors

Abstract

Nowadays, electronic, magnetic and optical properties of (III, Mn)V diluted magnetic semiconductor (dms) is a frontline research topic. This emerging research area, inspired us to give a great attention on the study of optical properties of these dmss. The work can be affirmed by calculating optical conductivity of the aforementioned dmss, particularly for the prototype, and for its base semiconductor. Hence the focus area of the study is to determine optical, magnetic and electronic properties using quantum concepts and quantum mechanical models such as linear response theory of Kubo formalism, Kohn-Luttinger Hamiltonian (theory), and Green function. In addition to these models, analytical calculations could be treated using perturbation theory of approximation, Fermi golden rules and Kramers-Kronig relations. Having all these models and analytical techniques, optical conductivity will be related as the product of the incorporated magnetic ion concentration and that of the reciprocal of the square root of photon energy in the infrared spectrum. All in all the results obtained fairly fits with others theoretical and experimental reports. Therefore, the findings indicated that there is a promising advancement of optoelectronic device functionalities, laser or spectroscopic experiments to provide background information about the optical linear response functions, high efficiency solar cells and thin film fabrications, magneto-optic materials determinations.
