Deposition of iron selenidenanocrystals and thin films from tris(N,N-diethyl-N′-naphthoylselenoureato)iron(iii)

Abstract

The complex tris(N,N-diethyl-N′-naphthoylselenoureato)iron(III) was synthesised and its X-ray single crystal structure determined. Thermolysis of this complex in oleylamine at all temperatures produced nanocrystals of FeSe₂ whereas Aerosol Assisted Chemical Vapour Deposition produced FeSe thin films on silicon substrates. Nanocrystals and thin films were characterised by powder X-ray diffraction (p-XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), and transmission electron microscopy (TEM).
