Registration Date 27-01-2022 Organization Yuriy Fedkovych Chernivtsi National University popup.description2  The formation and study of structured vector optical fields was carried out in order to create systems for controlling the movement of nanoparticles; new methods were developed and original systems of two-dimensional polarization-phase and diffusion tomography of diffuse layers of biological tissues and films of biological fluids were tested; constructed consistent quantum theory of energy spectra renormalized by interaction with phonons of all branches in nanostructures as the main constituent elements of modern infrared quantum cascade detectors; detectors and photodetectors of high-energy radiation based on cadmium telluride and its solid solutions with specified and reproducible electrical, photoelectric and detecting properties have been created; regularities were established for the formation of stable structural and phase states, as well as transitions between them in nanosystems of various measurability and nature (semiconductor nanoheterostructures, catalytic nanoparticles, single-walled carbon nanotubes, molecular quasi-magnetic materials), taking into account internal interactions and external factors; developed their schemes of asymptotic and numerical-analytical methods and their justification for wide classes of regularly and singularly perturbed differential-difference and differential-functional equations.
