Data confidence 85 high

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

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/Co0.65Zn0.35 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 Co0.65Zn0.35 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.
