A new theoretical method to study super-multiperiod superlattices has been *** method combines the precision of the 8-band kp-method with the flexibility of the shooting method and the Monte Carlo *** method was applied to examine the finest quality samples of super-multiperiod Al_(0.3)Ga_(0.7)As/GaAs superlattices grown by molecular beam *** express photoreflectance spectroscopy method was utilized to validate the proposed theoretical *** the first time,the accurate theoretical analysis of the energy band diagram of super-multiperiod superlattices with experimental verification has been *** proposed approach highly accurately determines transition peak positions and enables the calculation of the energy band diagram,transition energies,relaxation rates,and gain *** has achieved a remarkably low 5%error compared to the commonly used method,which typically results in a 25%error,and allowed to recover the superlattice *** retrieved intrinsic parameters of the samples aligned with XRD data and growth *** proposed method also accurately predicted the escape of the second energy level for quantum well thicknesses less than 5 nm,as was observed in photoreflectance *** new designs of THz light-emitting devices operating at room temperature were suggested by the developed method.

A universal regression-tensor approach is developed in the mathematical modeling of optimal parameters of chemical-technological process of complex mechanical products. The testing of developed algorithms was performed on the example of multi-factorial process of low-temperature sulfur-chromium plating of precision mechanical parts.
