Influence of temperature and deposition methods on the structural properties of CdTe nanocrystals

Abstract

The formation of cadmium telluride nanocrystals from sulfate and chloride solutions by the method of electrochemical and chemical deposition into a track template a-SiO 2 /Si-n is considered. It was found that after chemical deposition in a sulfate solution, CdTe nanocrystals with a cubic crystal structure are formed in the nanopores of the template, with an increase in the solution temperature, the results of X-ray diffraction analysis showed that CdO nanocrystals with a hexagonal structure are formed. The study of the current – voltage characteristics of the structure with the CdO monophase made it possible to estimate the number of grain boundaries and the height of the potential barrier, and n-type conductivity.
