Lashkaryov Institute of semiconductor physics popup.description2  This scientific work is devoted to the improvement of existing and development of new effective techniques for the production of low-dimensional semiconductor structures, in particular Cu2ZnSnS4 nanocrystals (NC), as well as partial or complete replacement of cuprum ions with arsenic and barium ions for further use in construct. The object of study is colloidal solutions of Cu2ZnSnS4 The purpose of the work is to develop methods for obtaining semiconductor nanocrystals (NCs) of Cu2ZnSnS4 composition on the basis of colloidal synthesis, as well as methods for partial or complete substitution of cuprum ions with arsenic and barium ions, study of chemical processes occurring in the process of synthesis and study of material properties for a photo of the absorbing layer in the solar cells. Research Methods - Raman spectroscopy. The results of the study - by the method of colloidal synthesis in aqueous solutions, stable solutions of NC Cu2ZnSnS4 were obtained and the influence of the impurities of argentium and barium and the presence in the reaction medium of NC CdTe, NC Au, NC Ag on the optical properties and structure of the obtained structures were determined. Keywords: nanocrystals, colloidal synthesis, optical properties, Raman spectroscopy. Product Description popup.authors Hreshchuk Oleksandr M. Kapush Olha A.
