• . This may partly explain the insufficient metal content achieved when using CVD precursors in FEBID [18]. In this context, efforts have been made to design gold precursors optimized for FEBID. Arguably, the most noticeable of these are chloro(carbonyl)gold(I) (AuICl(CO)) [22] and chloro

Keywords: Au(I) precursors; focused electron beam-induced deposition (FEBID); gold-NHC; gold precursors; nanofabrication; N-heterocyclic carbene; Introduction Focused electron beam-induced deposition (FEBID) is a nanofabrication technique that allows for the growth of three-dimensional free-standing

• applications from plasmonics [10] to optoelectronics [13]. Gold FEBID precursors (Figure 1) have had a similar history as other metal precursors, as the first tested compounds were taken from the existing library of gold precursors for chemical vapour deposition (CVD). The first compounds tested were gold

• ]. 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

• properties? In this paper we present a thorough study of organometallic gold precursors for FEBIP. Three Au(I) complexes, ClAuCO, ClAuPMe3 and MeAuPMe3, are characterized using scanning electron microscopy. The crystal structure of MeAuPMe3 was determined using single crystal X-ray diffraction and compared

• with a range of Au complexes. We combine these results with density functional theory calculations of ClAuCO, ClAuPF3, CF3AuCO, ClAuPMe3 and MeAuPMe3. The complexes are shown in Figure 2. Combining these experimental and theoretical datasets we elucidate the design rules for gold precursors. Finally

• different surface mechanisms prevented the direct application of the methods used for Pt purification to Au purification. These differences between the platinum precursor MeCpPtMe3 and the acetylacetonate-based gold precursors Me2-Au-acac, Me2-Au-tfac, and Me2-Au-hfac become evident by the fact that atomic
