Abstract

The boundary conditions of formation of tin (II) selenide and its hydroxide have been defined by means of calculation of ionic equilibriums with the use of thermodynamic constants for “tin chloride − sodium citrate − sodium hydroxide − thiocarbamide” system, taking into account the crystallization factor. The induction period was detected on the kinetic curves deposition of tin(II) sulfide by thiocarbamide. It demonstrates an active role of colloidal hydroxide component of tin(II) during the formation of a solid phase SnS. AFM-investigation of SnS layers at different stages of growth was carried out using fractal formalism. It has been shown that the nucleation and growth of the SnS films occur by the mechanism of cluster-cluster aggregation.
