Erratum to: Effect of deposition energy on the microstructure and phase purity of pulsed laser deposited iron fluoride thin films

Conversion material electrodes, such as FeF 2 , possess the potential to deliver transformative improvements in lithium-ion battery performance because they permit a reversible change of more than one Li-ion per 3d metal cation. Nanostructured thin films provide a model platform for obtaining basic insight to the structural and chemical underpinnings of the phase conversion processes, provided that they can be grown with a high degree of phase purity and the required microstructure. The results from X-ray diffraction and scanning and transmission electron microscopies together with electron energy loss spectroscopy indicate that at low supersaturation and growth rate, porous films and secondary phases are obtained. Good phase purity and dense nanostructured films were obtained at high surface supersaturation. The growth mechanism is three dimensional and is governed by direct supersaturation of the growth surface and the number of stable critical nuclei formed at a given substrate temperature.
