Creation of ZnSe nanoclusters in a silicon dioxide track template on silicon

Abstract

In this work, we study the formation of zinc selenide nanocrystals during chemical deposition into a-SiO2/Si-n track template. For the first time, zinc selenide nanocrystals were obtained by chemical precipitation in an aqueous alkaline medium using sodium selenosulfate as a source of Se ions. The deposition was carried out at a temperature of t = 75°C for 40 min. The morphology was observed using scanning electron microscopy, and the crystalline phase was studied using X-ray diffraction analysis. To confirm the obtained ZnSe phase by X-ray diffraction analysis, we performed elemental analysis on a TM3030 scanning electron microscope. The crystalline phase of the sample is a cubic structure (sphalerite) with space group F-43m. The unit cell parameters are: a = 5.592081 Å and corresponds to the results of other works.
