• represents perhaps the “cleanest” approach since it probes the reaction of one precursor molecule with at most one electron, without environmental influences (e.g., precursor–precursor or precursor–substrate effects). The possibility of making iron nanostructures is important mainly because of their magnetic

The further improvement of iron deposition can, however, be tackled by rational design of the precursor molecules
