A mathematical model the solutions of which make it possible to effectively calculate the electronic spectrum in nitride semiconductor nanosystems with spherical geometry - quantum dots is proposed. An approach is formulated and substantiated for taking into account the components of the electronic Hamiltonian due to the influence of correlation effects, size quantization effects, and internal fields arising in nitride semiconductors due to their anisotropy. Calculations of the electronic spectrum and its dependencies, performed on the basis of the proposed model, show good agreement between the obtained and experiment results in a wide range of changes in the geometric parameters of the nanosystem under study.
