Electrons as Invisible Ink A SiO x surface can be locally activated with a focused electron beam (1) such that subsequently dosed [Fe(CO) 5 ] decomposes (2) and autocatalytically grows to pure Fe nanocrystals (3) at predefined positions until the precursor supply is stopped. In their Communication on page 4669 ff., H. Marbach et al. describe how the two‐step process might be the starting point of a novel way to generate nanostructures (see the 3D representation of the SEM data in the background).
