Low energy electron-induced decomposition of (η3-C3H5)Ru(CO)3Br, a potential focused electron beam induced deposition precursor with a heteroleptic ligand set

Here we describe in detail low energy electron induced fragmentation of a potential focused electron beam induced deposition (FEBID) precursor, π-allyl ruthenium tricarbonyl bromide, i.e. (η 3 -C 3 H 5 )Ru(CO) 3 Br, specially designed to allow comparison of the effect of different ligands on the eff...

Description
Summary:Here we describe in detail low energy electron induced fragmentation of a potential focused electron beam induced deposition (FEBID) precursor, π-allyl ruthenium tricarbonyl bromide, i.e. (η 3 -C 3 H 5 )Ru(CO) 3 Br, specially designed to allow comparison of the effect of different ligands on the efficiency of low energy electron induced fragmentation of FEBID precursors. Specifically, we discuss the efficiency of dissociative electron attachment (DEA) and dissociative ionization (DI) with respect to electron-induced removal of the allyl, bromide and carbonyl ligands. We place this in perspective with a previous surface study on the same precursor and we propose a design strategy for FEBID precursor molecules to increase their susceptibility towards DEA. Low energy electron induced fragmentation of (η 3 -C 3 H 5 )Ru(CO) 3 Br is reported in relation to the suitability of different ligands in the design of focused electron beam induced deposition precursors.
