Purpose of research of - technology of growing of new experimental geteroepytaksyal'nykh structures with quantum pits by the method of gas epytaksyy, creation and research of new oxide-ceramic materials with not omycheskoy conductivity. Research methods are the analysis of optical properties of standards of experimental geteroepytaksyal'nykh structures by the methods of luminescent and eksytonnoy spectroscopies, optical and electronic photomicrograph, rentgenodyfraktsyonnyy analysis, statistical analysis of electric descriptions temperature to the zavysymostey capacity and electric conductivity. Ceramic structures were studied based on the metal oxides ( in particular, such as ZnO, SnO2 and In2O3 with various additives ) heteroepitaxial (in particular such as ZnO / GaAs, ZnSe / GaAs, ZnS / GaAs) quantum-well structure , and on the basis of oxides, and metal chalcogenides ( in particular, such as ZnO, ZnSe, ZnS). For heteroepitaxial experimental and quantum-well structures using a method of photostimulated gas epitaxy . The influence of technological factors on the experimental structures. First obtained and studied low-voltage varistor ceramics based on tin dioxide with a sufficiently high nonlinearity of current-voltage characteristic . Elektromigratsionnaya considered degradation model of metal oxide varistor structures. Studied the electrical conductivity of the oxide - indium ceramics with additives Bi2O3 and B2O3, which has sublinear current - voltage characteristics . The dependence of the electrical resistance of polyethylene composite materials - graphite on the thickness and temperature. Experimental evidence on the formation of the transition phase in the contact region of graphite - polyethylene. It is shown that ZnO -based ceramics with the addition of Ag2O is possible to manufacture sensors to couples alcohols. Organizations are a potential user are developers and manufacturers of electronic devices. The possible market of consumption includes application of the created materials in the devices of molectronics and defence of apparatus from the overloads by a current and tension. Can be drawn on results for development of new and improvements of existent ceramic touch-controls and nonlinear elements, for creation of new devices mykro- and optoelektronyky. The got results answer a world level. Validifys by the use of standard methods of measuring of electric properties of standards. Authenticity, exactness and correctness of researches, is guaranteed by multiple verification and repetition of results. Product Description popup.authors Іванченко О.В.
