description: This work is devoted to considering the effect of a Group 6 impurity, Tellurium, in GaAs and considering a complex vacancy trigon defect caused by the introduction of this impurity. This work is an attempt to apply the Jahn-Teller molecule model to explain the observed photoluminescence. The following tasks were set to solve: - studying of reviews on the physics of defects in semiconductors and the theory of deep levels in crystals. - Ascertainment of the role of impurities, giving deep levels, on the emission and absorption of light in GaAs. The Jahn-Teller theorem for molecules and for defective complexes. - Application of the anisotropic complex model to the VaGaTeAs vacancy defect in GaAs. Calculation of the equilibrium configurations of a defect in model of the problem (Ð + Ð1) â Ðµ for a trigon complex and wave functions of localized electrons in the approximation of infinitely heavy masses. - Evaluation of the parameters of the problem and comparison with experimental data. The calculation of the minimum of the adiabatic potential and all calculations were made in the Matlab 2017 environment. Because of the results obtained in the calculation, we can say that the model considered in the work and its application for calculating the angle of orientation of the emitting and absorbing dipoles makes it possible to reduce the set of parameters considered in the problem. The obtained values of the angles for some sets of parameters fit into the experimentally observed values.
