Iron Sulfide (FeS2) Thin Films From Single-Source Precursors by Aerosol-Assisted Chemical Vapor Deposition (AACVD)

Dialkyl (or mixed alkyl)-dithiocarbamato iron(III) complexes have been used for the deposition of iron sulfide thin films using chemical vapor deposition techniques. The single-source precursors used in this work have been prepared by the reaction of FeCl3with dialkyldithiocarbamate sodium salts and characterized by a number of analytical techniques. Good quality thin films of FeS2 have been prepared from the single-source metal organic precursor, [Fe(S2CNMeiPr)3], by AACVD. XRD patterns of the films indicated crystalline iron sulfide (FeS2) grown at between 375 – 450 °C. SEM images show the films to have reasonable morphology and to be crystalline.
