• collision experiments. Negative ions that are produced in the reaction area after the electron–molecule interaction are extracted from the collision area by a small draw-out field (ca. 0.5 V·cm−1), then analyzed by the QMA and finally detected using a single-pulse counting technique. The electron energy

• spectrometer (QMS). Both positive and negative ions resulting from the electron–molecule interaction are analyzed and detected using the quadrupole mass spectrometer. The flow of the molecular beam can be controlled with a leak valve. The TEM is heated to 120 °C with two halogen lamps in order to avoid

• increase the metal content up to 80%. Energy transferred into the system by heating or via the electron–molecule interaction activates the desorption of volatile molecules from the surface and leads to rearrangement of the deposited structures. As a result, residual precursor molecules and fragments are

• induced decomposition of this precursor and how this is reflected in the relatively poor performance of H2FeRu3(CO)13 as compared to the structurally similar HFeCo3(CO)12. Keywords: dissociative electron attachment; dissociative ionization; electron induced deposition; electron molecule interaction

• containing moiety while a Ru−CO bond rupture leads predominantly to charge retention at the Ru3 base plane moiety. In this context, and to aid the proceeding discussion, we note that the observation window of our experimental setup is about 10 μs, which is the extraction time from the electron–molecule

• interaction region. Fragments that dissociate further after extraction do not maintain stable trajectories within the quadrupole mass filter and are thus not detected. This is about 50 μs, which is the approximate lifetime required for a fragment to be observed. We now turn to discuss the [M − Fe(CO)4 − nCO

• . Electron-induced dissociation: Many different electron–molecule interaction processes are relevant for FEBID. They can be summarized as shown in Table 1. Depending on the energy range, various different specialized instruments have to be applied to acquire absolute energy-dependent cross sections for these
