It provides a general description of the research conducted, and the sections of the report include descriptions of a number of studies and their results, which give an idea of the directions of research that have been included in the topic. First (Chapter 2), this is an interesting question of modern electronics, can devices based on "negative capacitance" be really created and used, in particular with ferroelectrics in the gate of a transistor? The general conclusion is that the hope that the effect of negative capacitance will help to reduce the subthreshold spread below the critical value for room temperature, and contribute to the further miniaturization of MOSFET transistors, is not realistic. Research has a practical focus. The second (Chapter 3), the question of local Volt-Ampere characteristics of 2D dichalcogenides of transition metals, reconstructed on the basis of scanning tunnel microscopy. This question is also of a practical orientation, generated by subtle experiments in the USA. The study of the change in the shape of a beam (rod) made of magneto-active elastomer (MAE) upon magnetization is described in Chapter 4. MAE is a substance with low elastic modulus, capable of plastic deformation, which is filled with ferromagnetic micro- or nanoparticles. The beam is fixed at one end and placed in a transverse magnetic field. Chapter 5 is devoted to the phenomenon of the dependence of the energy of the photoluminescence peaks of indirect excitons in a semiconductor double quantum well on the energy of the monochromatic photoexcitation quanta and attempts to interpret it. The task is motivated by research on CdMgTe / CdTe / CdMgTe / CdMnTe / CdMgTe. During the implementation of the topic, one monograph, 46 scientific articles, one application for "Useful Model" was submitted, and 20 reports were made at scientific conferences. Articles printed in journals indexed by WoS and/or Scopus.
