Study of the use of ionizing radiation for the modification of CoO/Co_0.65Zn_0.35 nanostructures

Abstract

The paper presents the results of a study of the influence of heavy ions Xe²²⁺ on the morphology, phase composition, structural and conductive characteristics of CoO/Co_0.65Zn_0.35 nanowires obtained by the method of electrochemical synthesis. As a result of the research, it was established that an increase in the irradiation fluence leads to a change in the phase composition, due to the decomposition of the oxide phase CoO and the predominance of Co_0.65Zn_0.35 substitution in the structure of the cubic phase of solid solution. It has been established that an increase in the irradiation fluence and a decrease in the oxide phase in the structure leads to a decrease in the concentration of dislocations and vacancies in the nanowires, which indicates a partial relaxation of defects as a result of irradiation. It is established that a change in dislocation and vacancy density leads to an increase in the value of specific conductivity and a decrease in resistance.
