• Nowadays, organometallic complexes receive particular attention because of their use in the design of pure nanoscale metal structures. In the present work, we present results obtained from a series of studies on the degradation of metal(II) bis(acetylacetonate)s induced by low-energy electrons. These slow

• precursor anion is very effective for the Co-, Ni- and Cu-containing organometallic complexes, in contrast to MnL2 and ZnL2 (Figure 1). These experimental observations may be related in part to the adiabatic electron affinity values of the neutral precursors, which have been calculated to be 1.456, 1.124

Although many different ligand architectures of gold organometallic complexes were tested as FEBID gold precursors, the effect of different substitutions in the core structure of the molecule on the composition and growth rate of deposits is still largely unexplored. Such studies may reveal groups or

Most FEBID precursors are organometallic complexes designed with the aim to obtain pure metal deposits. Normally, the metal content is quite limited, and the deposits are often

Depending on the tip, it has been observed, that the absolute CPD values recorded on NiO can vary by roughly ±100 mV. Therefore, in order
