Structures formed in single-walled carbon nanotubes (SWCNTs) are transforming the development of paramagnetic and optoelectronic materials – with possible uses, for example, in solar cells, light-emitting diodes, and MRI devices [1]. Due to their extremely small diameters (≈1nm), SWCNTs have an innate ability to alter the stoichiometry of materials without need for chemical reaction, by confining materials to 1 dimension of expansion (1 degree of freedom). This changes the oxidation states on the elements within the compound, thus changing the electromagnetic properties of the material. This project focuses on the compound Fe3GeTe2 ,where we present: methods of synthesis; SWCNT filling and cleaning; and imaging. It is found that the morphology this compound forms inside of SWCNTs is like that of other chalcogenides observed inside SWCNTs [2].
