Theoretical and experimental basis for the creation of a new class of sensors terahertz range

An algorithm for computer simulation of molecular dynamics. Recommended method for studying nanosystems based on the results of molecular analysis - dynamic analysis of the basic properties of nanomaterials. Recommended method for determining the spatial distribution of polarization in dielectrics active nanolayers. The technique of describing the processes of nucleation and growth of artificial nanodomenov. To analyze the size effects built microscopic model intracluster atomic dynamics of the sensitive layer of the sensor. The dependence of the internal energy of the cluster when the state of the substance. The resulting dynamic characteristics of the clusters with a variable number of atoms. Developed a thermodynamic model of the cluster material sensor. The calculations nanodomenov education, limiting density of their formation. This allows you to select the optimum conditions for the formation of stable arrays nanodomenov and determine the conditions of their individual switching elements. Making measurements of nanostructures pyroelectric materials, obtained three-dimensional image of the surface. To measure nanostructures pyroelectric materials recommended technique using methods of atomic force microscopy. Special methods of image processing to obtain information about the crystallographic surface nanolayers. The technique of imaging nanoparticles with an electron microscope, is recommended technique of reconstructing their structure. Recommended method descriptions polar-active properties of ferroelectrics- semiconductors with charged defects. The technological procedure for the preparation of nanocomposite layers based on active dielectrics that serve as sensing elements and define the basic parameters of terahertz sensors.
