Abstract

This article reports the synthesis of carbon nanotubes (CNTs) encapsulating iron (Fe) that would lead to formation of magnetic semiconductors, employing the arc discharge method. Morphology of the samples is studied from transmission electron microscope (TEM) imaging. Data is recorded by x-ray diffractometer (XRD) and identification of the sample constituent by energy dispersion x-ray (EDX). TEM images of metal added samples indicated that defects are completely removed after mono acidic treatment and open air oxidizing at 4000C for 15 minutes, leaving nano sized carbonaceous attached on surfaces of carbon nanotubes and catalyst particles encapsulated. This formation is recognized as a phenomenon at certain temperature. EDX examination shows that there is oxygen constituent remaining after purification along with iron and carbon, perhaps forming FeO during the reaction with water, indicating success in metal incorporation. This envisages that there would be formation of magnetic semiconductors where iron ions may take carbon cites in the CNTs of semiconducting characteristics, as can be revealed from experiments. This suggests that magnetic carbon nanotubes can be used for the spintronic application.
