Obtained multilayer structure GaN-GaAs on silicon substrates, which are formed on the basis of the periodic structure of thermal sensors. 106 K-1.ЧNanolayers BaTiO3, BaSrTiO3 thickness (70-800) nm have coefficients of thermal stability in the range (100-300) Dimensions of structural defects were in the grain boundaries, crystallites. The proposed techniques, methods and recommendations will provide an opportunity to optimize the processes of formation of ferroelectric nanostructures for thermal sensors with desired properties. The results will be used to develop and implement new models of thermal sensors. Forward-looking assumptions about the development of the object of research - the creation of sensors with novel properties for biology, chemistry, medicine, and devices for electronics, electrical engineering, energy and other industries.
