While the technique is well-established for various materials, the direct electron beam writing of silver is still in its infancy. Here, we examine and compare five different silver carboxylates, three perfluorinated: [Ag2(µ-O2CCF3)2], [Ag2(µ-O2CC2F5)2], and [Ag2(µ-O2CC3F7)2], and two containing branched substituents: [Ag2(µ-O2CCMe2Et)2] and [Ag2(µ-O2CtBu)2], as potential precursors for focused electron-beam-induced deposition. All of the compounds show high sensitivity to electron dissociation and efficient dissociation of Ag-O bonds. The as-deposited materials have silver contents from 42 at.% to above 70 at.% and are composed of silver nano-crystals with impurities of carbon and fluorine between them. Precursors with the shortest carbon-fluorine chain ligands yield the highest silver contents. In addition, the deposited silver content depends on the balance of electron-induced ligand co-deposition and ligand desorption. For all of the tested compounds, low electron flux was related to high silver content. Our findings demonstrate that silver carboxylates constitute a promising group of precursors for gas-assisted focused electron beam writing of high silver content materials. info:eu-repo/grantAgreement/EC/H2020/722149/EU/Low energy ELEctron driven chemistry for the advantage of emerging NAno-fabrication methods/ELENA This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 722149-ELENA info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.4 2023 MATERIALS SCIENCE, MULTIDISCIPLINARY 146 / 439 = 0.333 2023 Q2 T2 NANOSCIENCE & NANOTECHNOLOGY 62 / 141 = 0.44 2023 Q2 T2 CHEMISTRY, MULTIDISCIPLINARY 70 / 231 = 0.303 2023 Q2 T1 PHYSICS, APPLIED 47 / 179 = 0.263 2023 Q2 T1 0.798 2023 Chemical Engineering (miscellaneous) 2023 Q1 Materials Science (miscellaneous) 2023 Q2 8.5 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Höflich, Katja Madajska, Katarzyna Berger, Luisa Brockhuis, Leo Edwards, Thomas Edward James Kapusta, Czeslaw Szymanska, Iwona B.
