Experimental error of EDX is about 1%, so, you cannot say anything about vacancies.

Alexandre Cunha

Dear Zyoud

From my point of view, EDX is useful just to perform simple and rough elementar chemical analysis. As mentioend before, the % of error is a critical drawback. I reccomend you to search for XPS analysis. Then, you have a characterization technique that will provide elementar composition, molecular information (oxides, nitrides, etc) with a suitable precision for quantification.

Have a good work !!!!!
