Aim: To create an analytical theory of polar and electronic properties of LD-TMDs and its application for forecasting and optimizing the properties of LD-TMDs. Methodologies: Landau-Ginzburg-Devonshire theory, elasticity theory, electrodynamics, semiconductor theory, symmetry theory and molecular dynamics will be used to describe the polar and electronic properties of LD-TMDs, scanning probe microscopy, optical, IR and Raman spectroscopy, in particular surface-enhanced vibrational spectroscopy. Novelty: The successful implementation of the project will lead to a self-consistent analytical theory to describe the key mechanisms and physical nature of polar, electronic and structural properties of LD-TMD. During the second stage: 2.1. An analytical review of the literature on "Application of HB-DPM in nanoelectronics and biomedicine" and identified the properties of the studied materials that can be optimized for their latest applications. 2.2. The results of theoretical calculations of electrophysical and structural properties of HB DPM type MyM'1-yX2 and MXY, and their interaction with biological molecules are analyzed and generalized. The comparison with the experiment is made, the correlation and regularity are established. 2.3. Samples of the most promising HB-DPM and systems "HB-DPM - biological molecule" for which the selected polar, structural and spectral properties were studied by means of electrophysical measurements, SPM and vibrational spectroscopy were prepared. 2.4. Using the developed analytical theory and the results of numerical modeling, we learned to predict the effect of deformations of different types on the polar and electronic properties of HB-MX2.
