“…A great part of existing researches deals with determination of structural, optical, and electrical properties of Cd 1 -x Mn x Se single crystals and thin films [1][2][3]. However, there is a lack of studies on influence of defects on structural and optoelectronic characteristics of Cd 1 -x Mn x Se epitaxial films [4]. This article presents calculations of electronic band structure, density of states, band gap, and total energy of the ideal and defective Cd 1 -x Mn x Se semimagnetic semiconductors (0.01 ≤ х ≤ 0.07) by ab-initio method using the Density Functional Theory (DFT).…”

Ab initio calculations for studying electronic band structure of ideal and defective Cd 1 -x Mn x Se (0.01 ≤ х ≤ 0.07) semimagnetic semiconductors have been performed. It has been defined that with an increase in concentration of Mn in Cd 1 -x Mn x Se compound, there is a decrease in the band gap. Based on the results obtained we can conclude that ferromagnetic phase is more stable than antiferromagnetic one. It has been found that defects such as vacancy, interstitial atom, and Frenkel pair lead to an increase in the band gap, change in the total energy, and formation of local levels in the band gap.

Cd1-xFexS (x = 0.03) solid solutions were synthesized and thin films were obtained on their base by molecular beam condensation method. It was studied the effect of γ- irradiation on surface morphology, growth properties and crystal structure of obtained thin films. The characteristics of Cd1-xFexS (x = 0.03) solid solutions exposed to γ-rays at doses of 50, 100 and 150 kGy from 60Co source were characterized by XRD, SEM, EDX methods. XRD analysis showed that the orientation of crystal planes changes after γ-exposure. It was determined that the peak intensity of the (101) plane of Cd1-xFexS solid solutions increased with the radiation dose. Sizes of crystallites increased after γ-irradiation. Thus it is possible to manage some crystal properties with γ-irradiation. XRD investigations demonstrates, that thin films grown on glass substrates at substrate temperature Tsub=470 K were polycrystalline structure and thin films grown at substrate temperature Tsub =670K were monocrystalline structure.

The transmission spectra of γ-irradiated Cd1-xFexS (x=0.05) thin films were carried out to study the effect of γ-irradiation upon optical properties and dispersion parameters. It was found that the optical properties of Cd1-xFexS thin films were highly affected by the exposure to γ-irradiation. The optical absorption spectra showed that the absorption mechanism is a direct allowed transition. The optical energy gap increases with the increase in irradiation dose. The values of optical constants were affected obviously with the increase in irradiation dose.
